A sports car of mass 1000 kg can accelerate from rest to 72.
km/h in 6.6 s.
a) What would the average force of the car's engine be?
b) If the same force acts on 2000 kg car what is the
acceleration.
(a) Find average force
Given:
Mass of the car,
Initial velocity of the car,
Final velocity of the car,
To convert km/hr to m/s. Multiply by 1000, then divide by 3600.
Time,
Use the formula to find the acceleration
