Question

If an object is moving at `5 m/s` and accelerates to `35 m/s` over 10 seconds, what was the object's rate of acceleration?

Answer 1

Data:-

Initial Velocity`=v_i=5m/s`

Final Velocity`=v_f=35m/s`

Time Taken`=t=10s`

Acceleration`=a=??`

Sol:-

We know that:

`v_f=v_i+at`

`implies 35=5+a*10`

`implies 30=10a`

`implies a=3m/s^2`

Hence, the rate of acceleration is `3m/s^2`.
