Two playful cats are pushing on either sides of a 3.0 kg box that can move over a very slippery floor. The black cat pushes with a 9.0 N force, acting due east, while the yellow cat uses a 8.7 N force, pushing 49° north of west. What is the magnitude of the box's acceleration? Assume that the cats are pushing perfectly horizontally to the floor (no vertical forces).

A 3.0 kg toy car can move along an x axis; the figure gives F_x of the force acting on the car, which begins at rest at time t=0. The scale on the F_xs axis is such that the point F_xs = 15.0 N. What is p at (a) t = 4.0 s and (b) t = 9.0 s? (c) What is v at t = 4.0 s and (d) t = 9.0 s?
3. Workhorses You are working in a 19th century warehouse trying to move a 200 kg box across the floor. Previous workers have estimated that the force of friction exerted by the floor on a box of this size and type is 1000 N. You harness two horses to the box. Albert Horse pulls in a direction 10° west of north and Gwnedolyn Horse pulls in a direction 20° east of north. The box slides due north at a constant...
8) A car is pushing a large truck, such that both accelerate. Which is true? A) The contact force the car exerts on the truck is larger than the contact force the truck exerts on the car. B) The contact force the truck exerts on the car is larger than the contact force the car exerts on the truck. C) The non-zero contact force of the truck on the car is equal to the contact force of the car on...
