Question

A 60 kg sprinter has a momentum of +600 kg-m/s when he crosses the finish

line. What is his velocity?​

Answer 1

10 ms⁻¹

Step-by-step explanation:

The amount of momentum that an object has is dependent upon two factors

• mass of the moving object
• speed of motion

In terms of an equation,

Momentum (P) = Mass(m)×velocity(v)

P = m×v

600 = 60 × v ⇒ v = 10 ms⁻¹
