Question

Tha path that a football takes can be described by the equation h=25t-5t^2, where h is the height of the football at time t, in seconds.How high is the ball after 3 seconds?

Answer 1

The height of the ball after 3 seconds is 30 units

Here, we want to get the height of the ball after 3 seconds

What we have to do is to make a substitution

We simply go on to substitute the value of t by 3

We have this as;

$\begin{gathered} h=25(3)-5(3)^2 \\ h\text{ = 75-45} \\ h\text{ = 30 } \end{gathered}$
