Question1

Assume two boxes on a frictionless table are linked by a heavy cord of mass 1.0 kg. Compute acceleration (magnitude) of each box and the tension (magnitude) at each end of the cored, using the free-body diagrams. Imagine FP = 40.0 N, ma = 10.5 kg, and mb = 13.0 kg, and ignore sagging of the cord.

Question2

A car is approaching a hill at 30.0 m/s at what time its engine suddenly fails just at bottom of the hill. The car moves with a constant acceleration of 2.00 m/s2 while coasting up the hill.

(a) Write equations for the position along the slope and for the velocity as functions of time,taking x = 0 at the bottom of the hill, where vi = 30.0 m/s.

(b) decide maximum distance the car rolls up the hill.
