Problem Set C

 

Problem #19:

A 1378-kg car is skidding to a stop along a horizontal surface. The car decelerates from 34.2 m/s to a rest position in 3.99 seconds. Assuming negligible air resistance, determine the coefficient of friction between the car tires and the road surface. Enter a positive value that is accurate to the third decimal place. (If necessary, review the definition of and the equation for computing the acceleration.)
