Question

A football is kicked vertically upward from a height of 4 feet with an initial speed of 50 feet per second. The formula h equals 4 plus 50 t minus 16 t squared describes the ball's height above the ground, h, in feet, t seconds after it was kicked. Use this formula to find the ball's height 3 seconds after it was kicked.

Answer 1

4 + 50(3) - 16(3*3) = 4 + 150 - 16*9 = 154 - 144 = 10
