Use the law of conservation of energy to solve. A plastic saucer sled starting from rest at the top of a snow covered 75 m slope that has an angle of 19o . If the coefficient of friction is is 0.089, what is the ski's speed at the foot of the incline?

18.84 and 21.84 are both incorrect.

    1) Shayla is sliding in a sled from a top of a 5-m-high snow hill ( starting from rest.) At the bottom of the hill, her sled hits Tom, who falls into the sled. Toms's mass is the same as Shayla's and her sled altogether. What is the speed of the sled after Tom fell in? Neglect friction w/ snow. 2) You are standing by a smooth frozen lake, and longing to propel a snowball over the lake. In which...

    An object of mass m is at rest at the top of a smooth slope of height h and length L. The coefficient of kinetic friction between the object and the surface, μk, is small enough that the object will slide down the slope if given a very small push to get it started.Sam, whose mass is 75 kg , stands at the top of a 14-m-high, 90-m-long snow-covered slope. His skis have a coefficient of kinetic friction on snow...

    A skier, starting from rest, coasts down a slope that makes a 25.0o angle with the horizontal. The coefficient of kinetic friction between the snow and the skis is 0.200. The skier travels along the slope a distance of 11.4 m before skiing off the edge of a cliff. The skier falls a vertical distance of 3.80 m before landing on another downhill slope. Determine the speed with which the skier lands.
