A 20-g arrow traveling at 70 m/s hits a target and penetrates 36 cm before coming to rest. If the archer now uses another arrow with the same mass and fires it with half the initial speed, how far will this arrow penetrate into the same target, assuming the same frictional force?

A box of mass m = 9.00 kg is located at the top of a ramp of height h = 7.00 m, as shown in the figure. The coefficient of kinetic friction between the ramp and the box is μk = 0.6. You give the box a push so that it starts sliding down with an initial speed of 2.50 m/s. The box continues its motion on a rough horizontal surface for 15.00 m until it hits a spring of spring constant k = 300. N/m and fully compresses it by 50.0 cm before coming to rest. What is the coefficient of kinetic friction between the horizontal surface and the box?

A 60.0 kg skier starts from rest at the top of a ski slope 63.0 m high. (a) If friction forces do −10.9 kJ of work on her as she descends, how fast is she going at the bottom of the slope? (b) Now moving horizontally, the skier crosses a patch of soft snow where μk = 0.21. If the patch is 65.0 m wide and the average force of air resistance on the skier is 180 N, how fast is she going after crossing the patch? (c) The skier hits a snowdrift and penetrates 3.0 m into it before coming to a stop. What is the average force exerted on her by the snowdrift as it stops her?

Two professional skaters (Joe and Sue) start their routine by pushing off from a facing, stationary pose as shown in figure (a). The kinetic frictional force acting on their skates can be ignored while they are pushing against each other, however once they separate, the force of kinetic friction eventually brings them to a halt. As shown in figure (b), after the push-off, they move in opposite directions with different speeds. (a) (b) The magnitude of their acceleration is the same, but Sue glides 4 times as far as Joe before coming to rest. Determine the ratio of their masses mS/mJ. mS mJ =
