If a body travles 30 m in an interval of 2 s and 50 m in the next interval of 2s. Then the acceleration of the body is

A body covers 10 m in the first 5 s and 20 m in the next 5 s. Find its average speed.

A body moving with uniform acceleration travels 84 m in the first 6 s and 180 m in the next 5 s. Find : (a) the initial velocity, and (b) the acceleration of the body.

The velocity of a body of mass 2 kg moving in circle of radius 3 m at any time is 3 m//s. If its speed is increasing at the rate of 4 m//s^(2) then the net acceleration on the body is :

Solve the following examples: (numerical problems) A body moves in a straight line with a uniform acceleration. If the initial velocity of the body is 5 m/s and the velocity after 10 s is 15 m/s, find the acceleration of the body and

If the velocity of a body related to displacement x is given by v=sqrt(5000+24x) m/s, then the acceleration of the body is _______ m//s^(2) .

A body is moving with a uniform acceleration coverss 40 m in the first 4 s and 120 m in next 4s. Its initial velocity and acceleration are
