Q. A concrete highway curve of radius 60.0 m is banked at a 13.0^circ angle. What is the maximum speed with which a 1300 kg rubber-tired car can take this curve without sliding? (Take the static coefficient of friction of rubber on concrete to be 1.0.)

Q. Two horizontal forces, 229 N and 160 N, are exerted on a canoe. If the these forces are applied in the same directions, find the net horizontal force on the crate.
