A ball thrown up vertically returns to the person after 6 s.Find the velocity with which it was thrown up

A ball thrown up verically returns to the thrower after 6 s. Find (a) the velocity with which it was thrown up. (b) the maximum height it reaches, and (c ) its position after 4 s.

An object is thrown vertically upwards and rises to a height of 10 m. Calculate (i) the velocity with which the object was thrown upwards and (ii) the time taken by the object to reach the highest point.

An object is thrown vertically upward with a speed of 30 m/s. The velocity of the object half a second before it reaches the maximum height

A stone is thrown vertically upwards from the ground with a velocity 15 m/s. At the same instant a ball is dropped from a point directly above the stone from a height of 30 m. At what height from the ground will the stone and the ball meet and after how much time? (Use g= 10 m//s^2 for ease of calculation).

A ball is thrown vertically down from height of 40 m from the ground with an initial velocity 'v'. The ball hits the ground, loses (1)/(3)rt of its total mechanical energy and rebounds back to the same height. If the acceleration due to gravity is 10 "ms"^(-2) , the value of 'v' is

A stone is thrown vertically upward with a velocity of 30 m//s . How high will it rise? After how much time will it return to ground ? [Take g = 10 m//s^2]

A ball is thrown vertically downwards from a height of 20m with an intial velocity v_(0) . It collides with the ground, loses 50% of its energy in collision and rebounds to the same height. The intial velocity v_(0) is (Take, g =10 ms^(-2) )

A ball is thrown vertically upwards with a velocity of 49 m//s . Calulate (i) The maximum height to which it rises, (ii) the total time it takes to return to the surface of the earth.

A ball is thrown from rear end of the compartment to the front end which is moving at constant horizontal velocity. An observer A sitting in the compartment and another observer B standing on the ground draw the trajectory. They will have

A man throws balls with same speed vertically upwards one after the other at an interval of 3s. What should be the speed of throw so that more than two balls are in the sky at any time?
