Motorcycle travel 39.75 m while coming to a stop

Explanation:

We have equation of motion

v = u + at

Final velocity, v = 0 m/s, u = 15 m/s, t = 5.3 s

0 = 15 + a x 5.3

a = - 2.83 m/s²

Now we have the other equation of motion

v² = u² + 2as

0² = 15² - 2 x 2.83 x s

s = 39.75 m

Motorcycle travel 39.75 m while coming to a stop
