Question

An object is moving at a velocity of 30 m/s. It accelerates to a velocity of 55 m/s over a time of 12.5 s. What acceleration did it experience? v = vo + at

Answer 1

Given data:

*An object is moving at a velocity is v_0 = 30 m/s

*The given final velocity of an object is v = 55 m/s

*The given time is t = 12.5 s

The formula for the acceleration of the object is given by the equation of motion as

`\begin{gathered} v=v_0+at \\ a=(v-v_0)/(t) \end{gathered}`

Substitute the known values in the above expression as

`\begin{gathered} a=(55-30)/(12.5) \\ =2m/s^2 \end{gathered}`

Hence, the acceleration of the object is a = 2 m/s^2
