Question

A football is kicked vertically upward from a height of 7 feet with an initial speed of 50 feet per second. The formula h equals 7 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 1 second after it was kicked.

Answer 1

Explanation:

41

Answer 2

41 ft

Explanation:

The formula for calculating height above the ground is:

h = 7+50t-
`16t^(2)`

where h represents the height and t is for time after the ball is kicked, in seconds

so 1 second after the ball is kicked the height of the ball can be calculated thus:

`h=7+50(1)-16(1)^(2)`

=41 ft
