Question

A motorcycle engine provides 473.3 N of force for 11.9 seconds. If the rider and the cycle have a mass of 2,068.3 kg, determine the change in velocity.​

Answer 1

After 11.9 seconds, the velocity will increase by approximately 2.7 m/s

Step-by-step explanation:

Ignoring friction, we can simply say that the speed will increase by

11.9s × 473.3N / 2068.3kg

Which can be expressed as:

11.9s × 473.3kg·m/s² ÷ 2068kg

= (11.9 × 473.3 ÷ 2048.3) (kg·m/s² × s ÷ kg)

≈ 2.7 m/s
