Acceleration can be known from

2.

 A car is moving on a road when rain is falling vertically downward.  Rain will Strike

3.

 A body starts from rest and moves with constant acceleration. What is ratio of distance travelled by body during 4th and 3rd second ?

4.

The distance of a particle is increasing linearly with time `t` as `s=bt`. n acceleration of particle is

5.

A body is thrown upward and reaches maximum height. At maximum height 

6.

The area of time acceleration graph gives

7.

One body is dropped while a second body is thrown downward with an initial velocity of 10 metre per second simultaneously.  The separation between se two bodies is 18 m after a time

8.

A body moves with constant acceleration. Its velocity increases from 6 metre per second to 16 metre per second in 2 seconds The distance moved by body in se two second is

9.

A particle moves along x axis in such a way that its x-coordinate varies with time according to expression `x=(2-5t+6t^2)` metre. The initial velocity of particle is 

10.

A train moves on a straight line track. It covers first half of distance at a speed of 20 km per hour and or half of distance at a speed of 30 kilometre per hour. The average speed of train is
