Question

A runner with a mass of 70 kg accelerates from 0 m/s to 8 m/s in 9 s. Find the magnitude of the net force (in newtons) on the runner using the alternate form of Newton's second law. Round your answer to the nearest whole number.

Answer 1

Step-by-step explanation:

F = ma

F = m Δv / Δt

F = (70 kg) (8 m/s − 0 m/s) / 9 s

F ≈ 62 N
