Hello, i need help.
This is Work-Energy Theorum

A car moving at 50km/hr skids 15m with locked brakes. How far will the car skid (with locked brakes if the car moves at 100km/hr assume that the mass of the car is 500kg

Four times as far, 60 m. The mass does not matter. The kinetic energy was increased by a factor of 4. The skidding friction force stays the same.
