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) = -16t2 + 120t. what is a reasonable value of the domain, t?

a) -4 seconds

b) 1 second
