(smart answer). Two cars A and B are moving in same direction with velocities 30 m/s and 20 m/s respectively.when car A is at a distance d behind the car B, the driver of car A applies brakes producing uniform retardation of 2 m/s square . Two cars A and B are moving in the same direction along a straight horizontal road. What about in a parallel circuit? Get your answers by asking now. B should reduce to zero before car A undergoes the relative displacement of d w.r.t. Join Yahoo Answers and get 100 points today. Does this mean that car a's acceleration is greater than car b's? All rights reserved. Please help A$AP no rocky if you can! What should be done to speed up the computer? Asked by Sayoni Maiti | 4th Jun, 2014, 10:27: AM. there will be no collision when - Two cars A and B are travelling in the same direction with velocities V1 and V2 (V1 V2). A smartass answer (but correct) is NO as this is equivalent to Jet B deploying its parachute. Two cars are moving in the same directions in parallel lanes along a highway.

Thank you for taking the time to answer. With reference to the first answer if one car is ahead by 20kms then the acceleration may not be enough. This video provides expert tips and contains practice problems on relative ... Queries asked on Sunday & after 7pm from Monday to Saturday will be answered after 12pm the next working day. In this video you will learn about Relative motion. they are seperated from each other by a 5 km. A ball is dropped from an upper floor, some unknown distance above Tom's apartment.effects of air resistance. Answer :d (V 1 - V 2) 2 /2a But if the two cars are moving on the same line then a slight acceleration may take its velocity higher. There will be no collision when [...] physics help? Two cars are moving in the same direction with a speed of 45km/hr and a distance of 10km separates them.
At some instant, the instantaneous velocity of car A exceeds the instatneous rate of car B. not necessarily, think of 2 cars, car A moving at 100 m/s and car B at 25 m/s, lets sat car A accelerates at 10 m/s and car B at 20 m/s, car A is at a velocity of 100+10*5 = 150 m/s, car B at a velocity of 25 + 20*5 = 125 m/s, clearly car A is faster even though car B is accelerating harder. The pilot in Jet A fires his afterburners, but Jet B doesn't.

At some instant, the instantaneous velocity of car A exceeds the instatneous rate of car B. Two cars are moving in the same directions in parallel lanes along a highway. occasion: You and me are working an identical speed on a Parallel street (without delay street) hastily my speed will improve(im working speedier) So im working speedier than you, lol. Expert Answer: The relative speed between the two cars is zero as both are moving with same speed i.e. Dont exactly know what to do here.

!.

They are on parallel runways taking off at exactly the same time. In the next second Jet A is faster than Jet B, this is because of increased acceleration caused by the afterburners. In a series circuit, what happens to the resistance when one out of 2 bulbs is removed? ? Yes As acceleration must be greater than Bs. Show that to prevent a collision between A and B it is necessary that (v 1 > v 2) 2 < (2 d)
Solve as many as you can!! No B could be decelerating.

When car A is d distance behind the car B, the brakes on A are applied, causing retardation. If a car coming from the opposite direction meets these two cars at an interval of 6 minutes, its speed would be a) 45km/hr (b) 55 km/hr (c) 65km/hr (d) 75km/hr Show that to prevent a collision between A and B it is necessary that. At any given time their velocities (instantaneous velocities) will be identical, unless there is a change in the system. When the car A is at a distance d ahead of the car B, the driver of the car A applied the brakes producing a uniform retardation a. there will be no collision. Consider two identical jets on take off.

Acceleration due to gravity of g = 6.794 m/s2 and want to jump safely into the water below after leaping from a 9.00 meter high-cliff. At time t=0, they are side by side, passing a point O on the road. Thank you for taking the time to answer. Want a call from us give your mobile number below, For any content/service related issues please contact on this number, Two cars A and B are travelling in same direction with speed v1 and v2 respectively (v1 > v2 ). Two cars A and B are travelling in same direction with speed v 1 and v 2 respectively (v 1 > v 2).

Does this mean that car a's acceleration is greater than car b's? car B. It can be and can not be. Still have questions? When the car A is at a distance d behind the car B the driver of the car A applies brakes producing a uniform retardation a . sure A have been given speedier than B speed: distance travelled consistent with unit time Acelleration: The replace that occurs in an merchandise's speed or path in a definite quantity of time.

Prove that an electromagnetic plane wave satisfies Gauss' Law for magnetic fields.? two cars are moving in the same direction with a speed of 30 km/h. Contact us on below numbers, Kindly Sign up for a personalized experience. A traffic light is suspended by two cords.

third car moving in the opposite direction meet the two cars after an interval of 4 minutes.find the speed of the third car. Car A travels at a constant speed of 30m/s. Otherwise car B is decelerating. Depends on the position of the cars with respect to each other. When car A is d distance behind the car B, the brakes on A are applied, causing retardation . Here, in problem to prevent the collision of car A with B, the relative velocity of car A w.r.t. Click hereto get an answer to your question ️ Two cars A and B are travelling in the same direction with velocities vA and vB (vA>vB) .
