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

The height and width of each step of a staircase are 20cm and 30cm respectively. A ball rolls off the top of a stair with horizontal velocity v and hits the fifth step. The magnitude of v is (g=10 ms^(-2) )

A projectile is thrown with an initial velocity (v_(x)hati + v_(y)hatj) ms^(-1) . If the range of the projectile is double the maximum height , then v_(y)/v_(x) is
