A car starts from rest and moves with uniform acceleration a on a straight road from time `t=0` to `t=T`. After that, a constant deceleration brings it to rest. In this process the average speed of the car is

A car starts from rest and moves with a constant acceleration of 5 m//s^2 for 10 s before the driver applies the brake. It then decelerates for 5 s before coming to rest, then the average speed of the car over the entire journey of the car is

A particle accelerates from rest with uniform acceleration alpha then decelerates to rest witha constant deceleration beta . Find total displacement. Given time is T

A car starts from rest and moves with uniform acceleration for time t then it moves with uniform speed of 60 km/h for time 3t and comes to rest. Find the average speed of car in its total journey.

A car starts from rest and moves with uniform acceleration for time t then it moves with uniform speed of 60 km/h for time 3t and comes to rest. Find the average speed of car in its total journey.

A car starts from rest and moves with uniform acceleration for time t then it moves with uniform speed of 60 km/h for time 3t and comes to rest. Find the average speed of car in its total journey.

A car starts from rest and travels with uniform acceleration a, for some time and then with uniform retardation beta and comes to rest. If the total time of car is 't', the maximum velocity attained by it is given by

A car starts to move from rest with uniform acceleration 10 ms^(-2 ) then after 5 sec, what is its velocity?

A car starting from rest is accelerates at a constant rate alpha until it attains a speed v. It is then retarded at a constant rate beta until it comes to rest.The average speed of the car during its entire journey is

A car starting from rest is accelerates at a constant rate alpha until it attains a speed v .It is then retarded at a constant rate beta until it comes to rest. The average speed of the car during its entire journey is
