a 4000 lb car is travelling at 40 mi/h when its brakes are applied and it skids to rest. The skidding tires experience a friction force about .80 times the weight of the car. How far does the car go before stopping? Take the motion to be along a straight line.

since i'm trying to find its distance. Do i use d = .5 at^2?

2 boxes having mass m1= 1.0 and m2 = 2.0 kg are in contact with each other on a horizontal table. Friction between each block and the table is negligible. A horizontal force F is applied to m1, causing the blocks to accelerate to the right with a= 5.0 m/s^2.

a) What is the magnitude of F?

b) What are the forces of compression between the blocks?
