a. What is the kinetic energy of a 1500 kg car traveling at a speed of 30 m/s (≈ 65 mph)?
b. From what height would the car have to be dropped to have this same amount of kinetic energy just before impact?
c. Does your answer to part b depend on the car’s mass?
Step 1 of 4:
Our aim is to find the kinetic energy of the car traveling at the speed given.
The mass of the car m = 1500 kg
The speed v = 30 m/s
The kinetic energy is given by
The kinetic energy of the car is 675 kJ.
