Unformatted text preview: f s is the friction force, N g is the normal force with the ground and N w the normal force with the wall.) 2. A small ball rolls horizontally off the edge of a tabletop that is 1.20 m high. It strikes the floor at a point 1.52 m horizontally from the table edge. (a) How long is the ball in the air? (b) What is its speed at the instant it leaves the table? O man, mass M ladder, mass m wall a h β L 3. A 2.5 kg block is initially at rest on a horizontal surface. A horizontal force F of magnitude 6.0 N and a vertical force P are then applied to the block. The coefficients of friction for the block and surface are μ s =0.40 and μ k = 0.25. Determine the magnitude of the frictional force acting on the block if the magnitude of P is (a) 8.0 N, (b) 10 N and (c) 12 N. 4. A block of mass m = 2.0 kg is dropped from height h = 40 cm onto a spring of spring constant k = 1960 N/m. Find the maximum displacement that the spring is compressed....
