A ball rolls of the top of a stariway with a constant horizontal velocity u. If the steps are h meter high and w meter wide , show that the ball will just hit the edge of n^(th) step if n = (2hu^(2))/(gw^(2)) .

A ball rolls off the top of a stariway with a horizontal velocity magnitude 150 cm/sec. The steps are 20 cm high and 20 cm wide . Which step will the ball hit first ?

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 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).
