Problem 35P
Based on unit considerations alone, show that the power needed to accelerate a car of mass m (in kg) from rest to velocity V (in m/s) in time interval t (in s) is proportional to mass and the square of the velocity of the car and inversely proportional to the time interval.

QUESTION:
Problem 35P
Based on unit considerations alone, show that the power needed to accelerate a car of mass m (in kg) from rest to velocity V (in m/s) in time interval t (in s) is proportional to mass and the square of the velocity of the car and inversely proportional to the time interval.
ANSWER:
Step 1:
Mass of the car = m (in kg)
Initial velocity = 0 (in m/s)
Final velocity = v (in m/s)
Time interval = t (in s)
