In what direction do they move immediately after collision
A 1500-kg car moving north at 27.0 m/s is struck by a 2165-kg car moving east at 18.0 m/s. The cars are stuck together. How fast and in what direction do they move immediately after the collision?

A 77 kg person sits on a 3.5 kg chair. Each leg of the chair makes contact with the floor in a circle that is 1.7 cm in diameter. Find the pressure exerted on the floor by each leg of the chair, assuming the weight is evenly distributed.
A rope applies a horizontal force of 180 N to pull a crate a distance of 2 m across the floor. A frictional force of 60 N opposes this motion.
The child is acted on by his weight, the normal force from the slide, kinetic friction, and a horizontal rope exerting a 30 Newton force. How large is the normal force of the slide on the child?
