A ball is thrown vertically upwards from the ground and a student gazing out of the window sees it moving upward past him at `10ms^-1.` The window is at 15 m above the ground level. The velocity of ball 3 s after it was projected from the ground is [Take `g= 10 ms^-2`]

A football is kicked vertically upward from the ground and a student gazing out of the window sees it moving upwards past her at 5.00 m//s. The window is 15.0 m above the ground. Air resistance may be ignored. Take g=10 m//s^2. (a) How high does the football go above ground? (b) How much time does it take to go from the ground to its highest point?

A ball is thrown vertically upward with a speed v from a height h above the ground . The time taken for the ball to hit the ground is

A ball is thrown vertically upwards with a velocity of 20ms^-1 from the top of a multistorey building. The height of the point from where the ball is thrown is 25.0 m from the ground. How high will the ball rise?

A ball is thrown vertically upwards with a velocity of 20ms^-1 from the top of a multistorey building. The height of the point from where the ball is thrown is 25.0 m from the ground. How long will it be before the balls hits the ground? Take g=10ms^-2 [Actual value of g is 9.8ms^-2] .
