On a snowy day your car which is moving at 20 km/h skids 15 m with locked brakes.When moving at 120 km/h with locked brakes,your car would skid

Question

Quizplus · Accepted Answer

The distance a car skids with locked brakes is proportional to the square of its speed. So, if the speed increases by a factor of 6 (from 20 km/h to 120 km/h), the skidding distance increases by a factor of 6^2 = 36. Therefore, 15 m * 36 = 540 m.
