If a car's mass is 600 kg, and its speed is 10 m/s. And a scooter's mass is 80 kg, and the scooter's speed is 50 m/s.
Then which will require more force to stop it if the distance is the same?

Best ResponseYou've already chosen the best response.1I thought we used f = ma And then f = 600 x 10 f = 6,000 And f = 80 x 50 f = 4,000 So it would take more force to stop the car. Am I correct? :P

Best ResponseYou've already chosen the best response.2now the kinetic energy of the car is: 0.5 * 600*100=30,000 Joules whereas kinetic energy of scooter is: 0.5*80*2500=100,000 Joules

Best ResponseYou've already chosen the best response.2oops.. formula for kinetic energy is: \(KE=1/2 \cdot m \cdot v^2\)
