- Repeat the preceding problem, but this time, suppose that the work done by air resistance cannot be ignored. Let the work done by the air resistance when the skier goes from A to B along the given hilly path be —2000 J. The work done by air resistance is negative since the air resistance acts in the opposite direction to the displacement. Supposing the mass of the skier is 50 kg, what is the speed of the skier at point B ?arrow_forwardA skier starts from rest and slides downhill. What will be the speed of the skier if he drops by 20 meters in vertical height? Ignore any air resistance (which will, in reality, be quite a lot), and any friction between the skis and the snow.arrow_forwardAt the bottom of an air track tilted at angle , a glider of mass m is given a push to make it coast a distance d up the slope as it slows down and stops. Then the glider comes back down the track to its starting point. Now the experiment is repeated with the same original speed but with a second identical glider set on top of the first. The airflow from the track is strong enough to support the stacked pair of gliders so that the combination moves over the track with negligible friction. Static friction holds the second glider stationary relative to the first glider throughout the motion. The coefficient of static friction between the two gliders is s. What is the change in mechanical energy of the two-glider-Earth system in the up- and down-slope motion after the pair of gliders is released? Choose one.

- As shown in Figure P7.20, a green bead of mass 25 g slides along a straight wire. The length of the wire from point to point is 0.600 m, and point is 0.200 in higher than point . A constant friction force of magnitude 0.025 0 N acts on the bead. (a) If the bead is released from rest at point , what is its speed at point ? (b) A red bead of mass 25 g slides along a curved wire, subject to a friction force with the same constant magnitude as that on the green bead. If the green and red beads are released simultaneously from rest at point , which bead reaches point first? Explain. Figure P7.20arrow_forwardA skier leaves a ski jump at 15.0 m/s at some angle . At what speed is he traveling at his maximum height of 4.50 m above the level of the end of the ski jump? (Neglect air friction.)

(c) Its velocity is unchanged. (d) Its speed is unchanged. (e) More information is needed.arrow_forwardConsider a particle on which a force acts that depends on the position of the particle. This force is given by .

- A 96-kg crate, starting from rest, is pulled across a floor with a constant horizontal force of 350 N. For the first 15 m the floor is frictionless, and for the next 15 m the coefficient of friction is 0.25. What is the final speed of the crate?arrow_forwarda roller coaster track is in the shape of the parabola y= 80 -(x^2/20), where the lengths are in meters. A roller coaster begins at height 0 with an inital speed of forty meters per second. Thereafter, the speed of the roller coaster satisfies conservation of energy. ( We ignore the effects of friction) Where on the track is the magnitude of the normal acceleration greatest?arrow_forwardIn the figure a block slides along a path that is without friction until the block reaches the section of length L = 0.77 m, which begins at height h = 1.9 m, on a ramp of angle θ = 30 ˚. In that section the coefficient of kinetic friction is 0.460 . The block passes through point A with a speed of 8.2 m/s. If the block can reach point B (where the friction ends), what is its speed there, and if it cannot, what is its greatest height above A?arrow_forward
