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 = \(\frac{\text{6000}}{\text{1200}}\)
a = 5 m/s2
The acceleration of the car is 5 m/s2
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 x 1.5.
F = 450 N
The resultant force developed by the speed boat engine is 450 N.
