time to fall?
h = (1/2) g t^2
so
1 = 4.9 t^2 solve for t
then
d = u t
1.5 = u t solve for u
also need v at floor
v = g t = 9.81 t
speed = sqrt(u^2 + v^2)
angle down from horizontal = tan^-1(v/u)
a ball rolls off the edge of a tabletop 1m above the floor and strikes the floor at a point 1.5m horizontally from the edge of the table. Find the (a) time of flight (b) initial velocity, (c) final velocity just before it strikes the floor. Plsssss help
