Question

If a football is thrown from rest with an acceleration of 8.5 m/s2, and had an final

Answer 1

Answer:

t = 2.94 seconds

Explanation:

Given that,

The initial velocity of the football, u = 0

The final velocity of the football, u = 25 m/s

Acceleration, a = 8.5 m/s²

We need to find the time for which the football is accelerating. Let the time is t. We know that,

$a=\dfrac{v-u}{t}\\\\t=\dfrac{v-u}{a}\\\\t=\dfrac{25-0}{8.5}\\\\t=2.94\ s$

So, the football is accelerating for 2.94 seconds.
