Question

*20 POINTS*

A ball is thrown from 4 feet off the ground with a vertical velocity of 30 feet per second.

Complete the equation to model the height of the ball.
h= -16t
`^(2)` + ___ t + ___

Complete the table.

Answer 1

h=-16t^2+ 30t+4.

Explanation:

For the table you just plug in the t (time) into the equation. So for the first one we have 0 seconds. So you plug in the 0 where it says t. So the equation becomes h=-16*0^2+30*0+4. Which gives us 4 h(height). Then you keep pluging in the time into the equation.

Time t in seconds 0 .5 1 1.5 2

Height h in feet 4 15 18 13 0
