A rain drop of mass 1.00 g falling from a height of 1 km hits the ground with a speed of `50 ms^-1`. Calculate. the gain in K.E. of the drop.

A rain drop of mass 1.00 g falling from a height of 1 km hits the ground with a speed of 50 ms^-1 . Calculate. Is the gain in K.E. equal to loss of P.E.? If not, why?

A raindrop of mass 1.00 g falling form a height of 1 km hits the ground with a speed of 50 ms^-1 . Calculate. the loss of P.E. of the drop.

It is well known that a rain drop falls under the influence of the downward gravitational force and the opposing resistive force. The latter is known to be proportional to the speed of the drop, but is otherwise undetermined. Consider a drop of mass 1.0g falling from a height of 1.00km. It hits the ground with a speed of 50.0ms^(-1) (a) What is the work done by the gravitational force ?

A 5 kg ball is thrown upwards with a speed of 10ms^-1(g=10ms^-2) Calculate the maximum height attained by it.

A rain drop of radius 2 mm falls from a height of 500 nr above the ground. It falls with decreasing acceleration (due to viscous resistance of the air) until at half its original height, it attains its maximum (terminal) speed, and moves with uniform speed thereafter. What is the work done by the gravitational force on the drop in the first and second half of its journey ? What is the work done by the resistive force in the entire journey if its speed on reaching the ground is 10 m s^-1 ?

A ball of mass 50 g falls from a height of 10 m and rebounds to a height of 5 m.Find the impulse and average force between the ball and ground if both were in contact for 0.1 second.
