3) A soccer ball is kicked with an initial horizontal speed of 8m/s and an initial vertical speed of 6
m/s. Identify the following quantities and include one shortsentence to explain your answer using
the concepts of projectile motion (no calculations arenecessary). Assume that projection and
landing height are the same and neglecting air resistance (4pts):
a) The ball’s horizontal speed 0.5 seconds into its flightis:
because:
b) The ball’s horizontal speed midway through its flight is:
because:
c) The ball’s horizontal speed immediately before contact withthe ground is:
because:
d) The ball’s vertical displacement up is (circle one) greaterthan/less than/the same as the
vertical displacement down because:
e) The ball’s vertical velocity halfway through its flightis:
because:
f) The ball’s vertical speed immediately before contact with theground is:
because:
