U = hor speed = 30 cos 60 = 15
Vi - initial ver speed = 30 sin 60
= 26
get time upward
v + Vi - 9.81 t
0 = 26 - 9.81 t at top
t = 26/9.81 that is half total time
range = 2 * 15 * 26/9.81
A tennis ball is thrown with a velocity of 30m/s at an angle of 60^ of the horizontal calculate the time,m/s,and the range
