2. A skier weighing 800 N comes down a frictionless ski run that is circular (R-...
Starting from rest, a 31.6 kg child rides a 8.50 kg sled down a frictionless ski slope. At the bottom of the hill, her speed is 6.4 m/s . If the slope makes an angle of 14.1° with respect to the horizontal, how far along the hill did she slide on her sled?
Starting from rest, a 28.6 kg child rides a 8.75 kg sled down a frictionless ski slope. At the bottom of the hill, her speed is 7.2 m/s . If the slope makes an angle of 14.5° with respect to the horizontal, how far along the hill did she slide on her sled?
Starting from rest, a 30.6 kg child rides a 7.75 kg sled down a frictionless ski slope. At the bottom of the hill, her speed is 6.0 m/s . If the slope makes an angle of 13.3° with respect to the horizontal, how far along the hill did she slide on her sled? Child on a sled sliding down a slope from right to left. distance= __________
12. A 62 kg skier is moving at 6.5 m/s on frictionless horizontal snow-covered plateau when she encounters a rough patch 3.50 m long. The coefficient of kinetic friction between this patch and her skis is 0.30. After crossing the rough patch and returning to friction free snow, she skis down an icy frictionless hell 2.5 m high. A) How much work is done by friction in crossing the patch? B) How fast is the skier moving when she gets...
An 90 kg skier starts from rest at the top of a ski run. She quickly finds herself going fast down the icy (essentially frictionless) hill. At the base of the hill she is unable to stop. She skis across an icy deck, through the open doors of the ski lodge; across the concrete floor of the rental shop before coming to rest against the back wall of the shop. The height of the hill is 150m, the deck and...
A skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 8.9° with the horizontal. The rope moves parallel to the slope with a constant speed of 1.1 m/s. The force of the rope does 640 J of work on the skier as the skier moves a distance of 5.9 m up the incline. (a) If the rope moved with a constant speed of 2.4 m/s, how much work would the force of...
A skier is pulled by a towrope up a frictionless ski slope that makes an angle of 12 degrees with the horizontal. The rope moves parallel to the slope with a constant speed of .0m/s. The force of the rope does 900J of work on the skier as the skier moves a distance of 8.0m up the incline. (a) If the rope moed with a constant speed of 2.0m/s, how much work would the force of the rope do on...
A skier approaches the base of an icy, frictionless hill with a
speed of Vo. As the skier travels up the slope, the skier slows
down. Find the HORIZONTAL and VERTICAL accelerations, NOT the
acceleration of the slope. Use the x-y axes shown with horizontal
rightward and vertical upward as positive. The initial velocity, Vo
= 10.2 m/s The angle of the hill, b = 15° Cannot figure this thing
out.I tried using -9.8Cos/Sin(15 but that was incorrect
A skier is gliding along at 3.0 m/s on horizontal, frictionless snow. He suddenly starts down a 10∘ incline. His speed at the bottom is 11 m/s . A) What is the length of the incline? Express your answer with the appropriate units. B)How long does it take him to reach the bottom? Express your answer with the appropriate units.
Starting from rest, a 29.2 kg child rides frictionless ski slope. At the bottom of the hill, her speed is 8.25 kg sled down a a 6.8 m/s. If the slope makes an angle of 15.5° with respect to the horizontal, how far along the hill did she slide on C her sled? 0.235 distance Momentum and Energy 2 Based on the previous question you can conclude that if two objects of different mass have the same magnitude of momentum,...
