A ball rolls of the top fi a strair way with horizonntal velocity of magnitude 1. 8 ms^(-1) . The steps are 0.20 m high and 0.02 m wide , Which step will the ball it first ? ( g = 10 m//s^@) .

A sphere rolls off the top of a stairway with a horizontal velocity of magnitude 200 cm/sec. The steps are 10 cm high and 10 cm wide. Which step will the ball hit first?(g=10 m//s^2 )

A small rolls of the top of a stairway horizontally with a velocity of 4.5 ms^(-1) . Each step is 0.2 m high and 0.3 m wide. If g is 10ms^(-2) , then the ball will strike the nth step where n is equal to (assume ball strike at the edge of the step).

A ball is rolled off along the edge of the table (horizontal ) with velocity 4 ms^(-1) .It hits the ground after time 0.4 s. Which one of the following statements are wrong ? ( g= 10 ms^(-2)).

A ball is thrown from a point in level with velocity u and at a horizontal distance r from the top os a tower of height h . At what horizontal distance x from the foot of the tower does the ball hit the ground ?

A ball is thrown from a point in level with velocity u and at a horizontal distance r from the top os a tower of height h . How must the speed and angle of the projection of the ball be related to r in order that the ball may just go grazing the top edge of the tower ?
