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?
By what percent must one increase the tension in a guitar string to change speed of waves on the string from 327 m/s to 376 m/s.
Two 53 {rm g} blocks are held 30 {rm cm} above a table. One of them is just touching a 50-long spring. The blocks are released at the same time. The block on the left hits the table at accurately the same instant as the block on the right first comes..
