A ball rolls off top of a staircase with a horizontal velocity u m s^-1 . If the steps are h metre high and b mere wide, the ball will just hit the edge of n th step. Find the value of n .

Velocity at a general point P(x, y) for a horizontal projectile motion is given by v=sqrt((v_("x")^(2)+v_("y")"^(2))),tan alpha=(v_(y))/(v_(x)) alpha is angle made by v with horizontal in clockwise direction Trajectory equation for a horizontal projectile motion is given by x=v_(x)t=ut y=- (1//2)"gt"^(2) eliminating t, we get y=-(1//2)(gx^(2))/(u^(2) A ball rolls off top of a stair way with a horizontal velocity u m//s. If the steps are h m high and b meters wide, the ball will just hit the edge of nth step if n^(th) equals to

A ball rolls off the top of a stairway with a constant horizontal velocity u. If the steps are h metre high and w metre wide, show that the ball will just hit the edge of nth step if n = 2hu^(2)/gw^(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 rolls off top of a stair case with horizontal velocity u (m)/(s) if the steps are h meter high and b meter wide, the ball will just hit the edge of n^(th) step. Then value of n is:

A ball rolls off the top of a stairway with a horizontal velocity u . If the height and width of steps are b and h respectively and the ball hits the edge of n^(th) step, then n is equal to

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