<PRE><B>Question 847152</B>
Jake serves a volleyball with an initial velocity of 32 feet per second from 4.5 feet above the ground at an angle 0f 35 degrees. 
a) Write parametric equations to model the situation.
h(t) = -16t^2 + 32t + 4.5
--------------------------------------- 
b) How long will the ball travel before it hits the ground?
Solve -16t^2+32t+4.5 = 0
t = 2.13 seconds
