WebJan 30, 2024 · In this experiment, the frictional resistance, F, acting on snow specimen was measured to be approximately 0.98 N. Therefore, the total energy, Ef, required to slide the snow specimen on the glass surface for 5 min amounts to Ef = Fvt = 0.98 N x 6.9 x 10 -2 m/s X 300 s = 20.3 J. WebThe coefficient of static friction between the sled and the snow is mu s. Find an expression for the maximum angle of the hill's slope measured upward from the horizontal in terms of mu s. How does your answer change if the rider is not on the sled? A sled and rider have a total mass 56.8 kg. They are at rest on a snowy hill.

WebThe coefficient of kinetic friction between the sled and the snow is 0.080. The sled accelerates at 0.85 m/s2 until it reaches a cruising speed of 15 km/h. Part A What is the team's maximum power output during the acceleration phase? Part B What is the team's power output during the cruising phase? This problem has been solved! WebSep 27, 2013 · The coefficient of friction between the sleds and the snow is 0.10. If the tension in rope 1 is 150 N, what is the tension in rope 2? [Sled A, 100kg]---1---- [Sled B, 80kg]--2--Dog pulling This problem was solved here, but I want to know why I come up with different results. I see in the link that they did not account for the friction. sazs catering graphic designer

WebYou've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. You've been walking at a steady 1.5 m/s, and the rope pulls up on the sled at a 43 ° angle. You estimate that the mass of the sled, with your friend on it, is 61 Show transcribed image text Expert Answer 100% (1 rating) WebA team of dogs is pulling a sled directly south. The dogs pull with a combined force of 334 N, and the force of friction acts in the opposite direction with a magnitude of 87.0 N. If the sled weighs 91 kg, what will the speed of the sled be after 1.5 seconds? 4.1 m/s An asteroid has a mass of 8.55∗106 kg. WebBefore working with sleds and friction, have students perform this experiment, in pairs, to see friction at work. ...
