Question

A motorcycle moving at 13.2 m/s increases in speed to 25.7 m/s over a period of 8.6 s. If the motorcycle's mass is 352 kg, what net force in Newtons acts on the motorcycle?

Answer 1

Answer:

510.4 N

Explanation:

u = 13.2 m /s, v = 25.7 m/s, t = 8.6 s, m = 352 kg

Use first equation of motion

v = u + a t

a = (25.7 - 13.2) / 8.6 = 1.45 m/s^2

Use Newton's second law

F = m a = 352 x 1.45 = 510.4 N
