Question

The path that a football takes can be described by the euation h=25t-5t^2 where h is the height in meters, of the football, at t, in seconds. How high is the ball after 3 seconds?
h+25t-5^2
h= 25(3)-5(3)^2
h= 75- 45= 30 m

Answer 1

h = 25 t - 5 t ^ 2

Replace t with 3

h = 25 * 3 - 5 * 3 ^ 2

h = 75 - 5 * 9

h = 75 - 45 = 30 m

Answer 2

when will it hit the ground
