Question

A car of mass 1000 kg accelerates from rest to 20 m/s in 10 seconds. What is the magnitude of the pseudo force a passenger feels, pushing them back into their seat?

Options

• 1000 N

• 2000 N

• 50 N

• 200 N

Answer 1

2000 N

Explanation:

This result is obtained by first calculating the car's acceleration (a = (20 − 0)/10 = 2 m/s²) and then applying F = ma (1000 kg × 2 m/s²).
