Question

if a boy is running along a straight road with unuform velocity 3m/s find his acceleration after 15 minutes​

Answer 1

Answer:

0m/s^2

Both his speed (3m/s) and direction (on a straight road) are constant, meaning that his velocity is also constant. On a velocity-time graph, this would be represented by a straight, horizontal line at x= 3 (m/s). Acceleration is the change of velocity over time, and since there is no change in velocity, the answer is just 0 m/s^2.
