Given:

Acceleration = 5.7 m/s^2

Time = 7.2 seconds

Determine the speed.

Formula for acceleration:

a = v/t

v = (t)(a)

a = acceleration

v = velocity

t = time

Solution:

In order to find for v, we simply used the equation for v in terms of a.

v = ta

v = (5.7 m/s^2)(7.2 s)

v = 41.04 m/s

Final answer:

v = 41.04 m/s
