A vehicle with a mass of 1500 kg is decelerated at a rate of 5 m/s^2. How much force did this take?

Question

solve the problem using two
Different masses and explain how the inertia in the object affected the amount of work used to
accelerate that object in relation to the object’s mass.

Answer 1

Use Newton's 2nd law.

 

F = ma = (1500 kg)(-5 m/s²) = ? N

 

The negative sign means the force opposes the direction of motion.  There is not sufficient information to answer the rest of the question.
