In Figure, a block with mass m = 1 kg is released from height h1= 12 m. Its path is without friction until it reaches the path with first length d1= 2 m, where the friction force between B and C is fs1= 8 N, and until it reaches the path, where the friction force between E and F is fs2= 6 N.

The skateboarder starts down the left side of the ramp with an initial speed of 6.3 ft/s. If nonconservative forces, such as kinetic friction and air resistance, are negligible, what would be the height "h" of the highest point (in meters) reached by the skateboarder on the right side of the ramp?
A block is placed on a frictionless ramp at a height h; of 14.5 m above the ground. Starting from rest, the block slides down the ramp. At the bottom of the ramp, the block slides onto a frictionless horizontal track without slowing down. At the end of the horizontal track, the block slides smoothly onto a second frictionless ramp. 01 = 43.3° 02 = 19.5° How far along the second ramp does the block travel before coming to a momentary stop, as measured along the incline of the ramp? distance traveled along second ramp: m After the block comes to a complete stop on the second ramp, it will then begin moving back down the second ramp.

Chapter 08, Problem 022 Your answer is partially correct. Try again. A 54 kg skier starts from rest at height H = 23 m above the end of a ski-jump ramp (see the figure). As the skier leaves the ramp, his velocity makes an angle of e = 27° with the horizontal. Neglect the effects of air resistance and assume the ramp is frictionless.

A boy shoves his stuffed toy zebra down a frictionless chute. It starts at a height of 1.27 m above the bottom of the chute with an initial speed of 1.07 m/s. The toy animal emerges horizontally from the bottom of the chute and continues sliding along a horizontal surface with a coefficient of kinetic friction of 0.223. How far from the bottom of the chute does the toy zebra come to rest? Assume g = 9.81 m/s2. E
Chapter 07, Problem 042 GO The figure shows a cord attached to a cart that can slide along a frictionless horizontal rail aligned along an x axis. The left end of the cord is pulled over a pulley, of negligible mass and friction and at cord height h = 1.5 m, so the cart slides from x, = 5.0 m to x, = 2.0 m. During the move, the tension in the cord is a constant 29.0 N. What is the change in the kinetic energy of the cart during the move?
