Question

If the velocity of a body varied uniformly from 10 ms-1 to 25 ms-1 during a time interval of 5s what was the acceleration of the body?

Answer 1

Acceleration = velocity change / time
a = 25 - 10 / 5
a = 15/5
a = 3

In short, Your Answer would be 3 m/s2

Hope this helps!

Answer 2

Acceleration of the body = $\frac{changeinvelocity}{time}                                            = \frac{25-10}{5}                                            = \frac{15}{3}                                            = 3m/s ^{2}$.

Hope this cleared your doubt. Have a great day/night ahead!
