Speed of a body depends on 

If a body is thrown up with an initial velocity u and covers a maximum height of h, then h is equal to

Average speed of a body is

A particle is projected up with a velocity of  $$\sqrt{29}\ ms^{-1}$$ from a tower of height 10m. Its velocity on reaching the ground is    $$ x $$ $$\ ms^{-1}$$. Find $$ x $$.

$$N/kg$$ is the unit of :

A stone is projected up with a velocity of $$4.9\ m/s$$ from the top of a tower and it reaches the ground after 3 s. Then the height of that tower is

The relationship between average speed, time and distance is

Two balls are dropped from height $$h_1$$ and $$h_2$$ respectively. What is the ratio of their velocities on reaching the ground is?

A freely falling body from rest acquires velocity V falling through a distance h. After the body falls through a further distance h velocity acquired by it is
