1) A tennis ball is lobbed at 30° to the horizontal at +10 m/s from a height of 0 m.
a) What is the initial velocity in the horizontal and vertical directions?
b) How long does the tennis ball take to reach the ground?
c) What distance (range) does the tennis ball travel?
d) What is the ball's maximum height?
e) If the initial horizontal velocity of the tennis ball was doubled how would this
change the trajectory?
