A ball thrown vertically upwards with an initial velocity of 1.4 m/s returns in 2s. The total dispalcement of the ball is

A ball is thrown vertically upwards with a certain velocity. Then

A ball is thrown vertically upwards with an initial velocity of 49 m s^(-1) . Calculate the time taken by it before it reaches the groung again (Take g= 9.8 m s^(-2) )

A ball is thrown vertically upwards with a velocity of 49 m/s. Calculate the total time it takes to return to the surface of the earth.

If a ball is thrown vertically upwards with a velocity of 40m//s , then velocity of the ball after 2s will be (g = 10m//s^(2))

If a ball is thrown vertically upwards with a velocity of 40m//s , then velocity of the ball after 2s will be (g = 10m//s^(2))

A ball is thrown vertically upward from the 12 m level with an initial velocity of 18 m//s. At the same instant an open platform elevator passes the 5 m level, moving upward with a constant velocity of 2 m//s. Determine ( g = 9.8 m//s^2 ) (a) when and where the ball will meet the elevator, (b) the relative velocity of the ball with respect to the elevator when the ball hits the elevator.
