Final answer:
The force exerted by the wheels on the ground to accelerate a 1500 kg car to 20 m/s in 8 seconds is 3750 N, which corresponds to answer option C.
Step-by-step explanation:
The question asks what force the wheels exert on the ground to accelerate a 1500 kg car from rest to a speed of 20 m/s in 8 seconds. To find the force, we first need to calculate the acceleration of the car using the formula a = ∆v/∆t, where ∆v is the change in velocity and ∆t is the time taken. With the given values, the acceleration (a) is 2.5 m/s2. After finding the acceleration, we apply Newton's second law, F = ma, to find the force exerted by the wheels. With a mass (m) of 1500 kg and the calculated acceleration, the force (F) is 3750 N. Therefore, the correct answer is C) 3750 N.
