A stone is projected vertically up from a point on the ground, with a speed of `20 m//s`. Plot the variation of followings with time during the entire course of flight –

A stone projected vertically up with velocity v from the top of a tower reaches the ground with velocity 2 v The height of the tower

A stone is dropped from the top of a 400 m high tower. At the same time another stone is projected vertically upwards from the ground with a speed of 50 m//s . The two stones will cross each other after a time

A stone is thrown vertically up from the tower of height 25m with a speed of 20 m/s What time does it take to reach the ground ? (g=10 m//s^(2))

A stone is projected vertically up from the ground with velocity 40 ms^(-1) . The interval of time between the two instants at which the stone is at a height of 60 m above the ground is (g = 10 "ms"^(-2))
