a) Evaluate and interpret $h(2)$.
$h(2) =$
? h(2) represents the height of the ball at time t=2 seconds. h(2) represents the time when the ball is at height 2 feet. h(2) means the ball was thrown from 2 feet above the ground.

b) Solve the equation $h(t) = 80$. Enter the smaller number first, if applicable. Interpret your solutions.
? t= h(t)=
? t= h(t)=
? These values of t are the times at which the ball is 80 feet above the ground. These values of t are the times at which the ball is on the ground. These values of h(t) are the heights at which the ball could be at time t=80 seconds.

c) When does the ball hit the ground after it is thrown?
At time $t =$
