Question

a 450 kg sports car accelerates form rest to 100 km/h in 4.8 seconds. what magnitude force does a 68 kg passenger experience during the acceleration

Answer 1

2604 N

Step-by-step explanation:

Convert km/hr to m/s: 100 km x 1000 m/km x 1 hr/3600 s = 27.8 m/s

a = Δv/t = (28.8 m/s - 0) / 4.8 s = 5.8 m/s²

F = ma = (450 kg)(5.8 m/s²) = 2604 N
