The initial velocity is : How do you solve the initial velocity step by step? I thought that the Vo would be 0 because at time t=0 the ball wouldnt be moving... Solution Ball must have some initial speed to move in projectile motion so that vi must not be zero Ball will move in projectile motion the time of flight t=2visin/g sin=1 t*g/2=vi (-6)(-32)/2=vi 96ft/sec=vi.

time t=0 the ball wouldnt be moving...
Solution
Ball must have some initial speed to move in projectile motion
so that vi must not be zero
Ball will move in projectile motion
the time of flight
t=2visin/g
sin=1
t*g/2=vi
(-6)(-32)/2=vi
96ft/sec=vi
