Angela Gordon · Answer 1

1. The magnitude of the force is 12 N

2. This can be solve using the formula D = rt

Where d is the distance, r is the speed and t is time

t = D / r

t = 120 mi / 60 mph

t = 2 hours

3. Acceleration = change in velocity / time

A = (15 m/s - 10 m/s) / 10 s

A = 0.5 m/s / s
