Question

What is the acceleration of a vehicle that speeds up from 20 m/s to 58.25 m/s 9 seconds

Answer 1

Acceleration is defined as the rate of change of velocity

It can be calculated as the ratio of change in the velocity to the time interval

i.e.

$\text{acceleration=}\frac{change\text{ in velocity}}{total\text{ time}}=\frac{58.25-20}{9}$

Which gives us acceleration = 4.25 m/s^(2)
