While on the golf course last weekend marc hit into the rough landing the ball behind a tall tree. his best option was to get it high enough to get over the tree and hopefully
come down in the fairway for his next shot. so with a mighty swing he hit the ball into
the air and was surprised to see the ball hit near the top of a 300 foot tall tower that
he had not noticed.
the formula is: h(x)= -16x^2 +20x where h is the height of the ball and
x is the number of seconds the ball is in the air.
how high did marc actually hit the ball?
