Q. A 1500 kg car skids to a halt on a wet road where coefficient of friction = 0.46.How fast was the car traveling if it leaves 68m long skid marks?

Q. A 4.9 block starts at rest and slides a distance d down a frictionless 25.0 incline, where it runs into a spring. The block slides an additional 20.0 before it is brought to rest momentarily by compressing the spring, whose spring constant is 435 . What is the value of d?

What is the distance between the point of first contact and the point where the block's speed is greatest?
