How do you calculate retarding force?
How do you calculate retarding force? 1. Find the accelerating and retarding (stopping) force: Accelerating force: First, find acceleration: 50 km/h is equal to 13.89 m/s (we calculated this with the speed converter). Retarding force: a = (0 – 13.89 m/s) / 8 s = -1.74 m/s2 Fr = 50 kg * -1.74 m/s2 = […]
