Sam is playing with his slingshot and launches a rock straight up in the air with an initial upward velocity of 120 ft/sec. Gravity slows the rock's upward velocity and it eventually changes directions and falls back down to the ground. The height of the rock is defined using the function h(t) = -162 +120t. What is a reasonable value of the domain, t?
A : 1 second
B : 90 seconds
C : -4 seconds
D : 5 seconds
