Brake is applied on a vehicle which then skids a distance of 16 m before coming to stop. if the developed average coefficient of friction between the tyres and the pavement is 0.4, then the speed of the vehicle before skidding would have been nearly

Answer 1

rake is applied on a vehicle which then skids a distance of 16 m before coming to stop. if the developed average coefficient of friction between the tyres and the pavement is 0.4, then the speed of the vehicle before skidding would have been nearly

Answer 2

Answer:

40kmph

Given S = 16m, f = 0.4

b = s = v^2/254×f

V = √254×f×s = √254×0.4×16 = 40.31 kmph
