Engineers are trying to improve a race car. their goal is to increase the acceleration of the car using the same engine. which change shows the best application of newton’s laws of motion to achieve this goal? a. increasing the inertia of the car b. decreasing the reaction force c. increasing the action force d. decreasing the mass of the car

d. decreasing the mass of the car

Explanation:

According to Newton's second law of motion the change in motion is proportional to the change in force being applied to a body. Which is denoted by

F = ma

Where F = The force being applied

m = Mass of the body

a = Acceleration of the body

When mass of the car will be decreased this means that the acceleration will increase given the force which the engine is providing remains the same.

b. lifting dumbbell weight at 20-degree angle from the body after a 45-degree angle
