A body A starts from the rest with an acceleration `a_1`. After 2 second another body B starts from rest with an acceleration `a_2` . If they travel equal distance in the 5th second after the start of A, then what will be the ratio `a_1 : a_2`.

A car starts from rest and moves with constant acceleration. The ratio of the distance covered in the nth second to that covered in n seconds is

A body starting from rest , moves with uniform acceleration . The distance covered by the body in time is proportional to

A particle experiences constant acceleration for 20 seconds after starting from rest.If it travels a distance S_1 in the first 10 second and s_2 in the next seconds, how s_1 and s_2 are related?

A truck starts from the speed from rest with an acceleration 1.5m/s^2 while a car 150m behind starts from rest with an acceleration of 2m/s^2 . How long will it take before both the truck and car side by side and how much distance is travelled by each ?

A balloon starts rising from the ground with an acceleration of 1.25m//s^2 . After 8s stone is released from the ballon. What distance the stone will cover?

A body moves along a straight line with acceleration 3m/s^2 for 2 seconds and then with acceleration 4 m/s^2 for 3 seconds . What is the average acceleration

A body starts from rest and acquires a velocity V in time T. The work done on the body in time t will be proportional to

A body moving with uniform acceleration describes 12m in the 3rd sec of its motion and 20m in the 5th second. Find the distance covered in the 10th second.

The acceleration of a particle starting from rest varies with time according to the relation a=-sw^2 sin wt The displacement of the particle at time 't' will be

A lift starts from rest with constant upward acceleration . It moves 1.5m in the first 0.4 secs. A person standing in the lift hold a packet of 2 kg by a string. Calculate the tension in the string during the motion.
