As my puppy Ragnar got older, I had to find ways to entertain him. Ragnar
loves to chase rubber balls, so I kick a ball, sending it over a 3 meter high
tree that is 14m away. The ball lands at the same level from which it was
struck after traveling a horizontal distance of 17.8 meters.
(A) If the ball left the ground 54 degrees above the horizontal and landed
2.24 seconds later, what was its initial speed?
(B) How high was the ball when it passed over the tree?
(C) What is the highest point reached by the ball?
(D) If I was to throw the ball instead of kicking the ball
from the ground, how would this affect the ball's time of
flight? Explain.
