Question 78 Exercise

A motorcycle moving with a speed of 5 m/s is subjected to an acceleration of 0.2 \mathrm{m/s^2} . Calculate the speed of the motorcycle after 10 seconds and the distance travelled in this time.

Answer:

Initial velocity, u = 5 m/s

Final velocity, v = ?

Acceleration, a = 0.2 \mathrm{m/s^2}

Time, t = 10 s

v = u + at = 7 m/s
