Question:
A 1,500 kg truck is travelling at an acceleration of 200 m/s², East. Find the force needed to accelerate the truck.
What is asked?
We're asked to find the force needed to accelerate a 1,500 kg truck travelling at an acceleration of 200 m/s² east.
What are the given?
Observing the problem, we have the following given:
What formula do we need to use?
The formula that we are going to use is a formula from Isaac Newton's second law of motion, i.e.:
Solution:
Therefore, we require a force of 300,000 N in order to accelerate a 1,500 kg truck to an acceleration of 200 m/s².
