Motion in A Str...

An object is thrown from  height of h, its covers height h in time T. After time T/2 where will be the object.

A man throws balls into the air one after another. He always throws a ball when the previous one thrown has just reached the highest point. The height to which each ball rises, if he throws 5 balls per second is $$(g = 10 ms^{-2})$$:

A ball is released from certain height h reaches ground in time T. Where will it be from the ground at time $$ \frac { 3T }{ 4 } ? $$

A man slides down a snow covered hill along a curved path and falls $$20$$m below his initial position. The velocity in m/sec with which he finally strikes the ground is? $$(g=10 m/sec^2)$$.

If we use plus and minus signs to indicate the direction of velocity and acceleration in one dimension, in which of the following situation does the object speed up?

An object is thrown from the height of 125 cm take g = 10 m/s. Find the ratio of distance covered by object in the 1 st and last 1 sec 

The motion of a particle of mass $$m$$ is describe by $$y = ut + \dfrac{1}{2} gt^2$$. Find the force acting on the particle.

The rate of change of velocity is:

A car initially travelling north at 5 m/s has a constant acceleration of $$ 2 m/s^2 $$ northward. How far does the car travel in the first 10 s?

A ball dropped from one metre above the top of a window, crosses the window in $$t_{1}\;s$$ . If the same ball is dropped from $$2\;m$$ above the top of the same window, time taken by it to cross the window is $$t_{2}\; s$$ . Then
