There is too little information to know
This graph is based on a rolling object with a mass of 2000 kg. At a speed of 80 m/s, the object has 1,000,000 J of kinetic energy. How much kinetic energy does it have when the speed doubles?
1,000,000 J
2,000,000 J
3,000,000 J
4,000,000 J
How much less kinetic energy goes an object have if it changes speed from 100 km/h to 50 km/h?
Kinetic energy does not decrease
Kinetic energy decreases by half
Kinetic energy decreases from 400 kJ to 200 kJ
Kinetic energy decreases from 400 kJ to 100 kJ
