Question

A car has a mass of 1200 kg, and an engine that can deliver a force of 6000 N. Find the acceleration of the car.

a = \frac{\text{F}}{\text{m}}

F = 6000 N

m = 1200 kg

a = \frac{\text{6000 N}}{\text{1200 kg}}

a = 5 m/s2

The acceleration of the car is 5 m/s2

Question

Find the resultant force developed by a speed boat engine, if the boat has a mass of 300 kg and can accelerate at a rate of 1.5 m/s2.

F = ma

a = 1.5 m/s2.

m = 300 kg

F = 300 kg x 1.5 m/s2.

F = 450 N

The resultant force developed by the speed boat engine is 450 N.
