A skier glides 2.4 m up a hill angled 30° above the ground. His speed slows from 8.2 m/s to 5.3 m/s. Determine the coefficient of friction of the hill with the skier. use grade 12 knowledge

A 75.0-kg skier takes 20.0 s to reach a speed of 25.0 𝑚 𝑠⁄from rest while descending a uniform 16.0° slope, as shownin the diagram to the right. The coefficient of frictionbetween the skier and the hill is a.bc x 10-d (only providethe values for a, b, c, and d). 16.0o

A professional skier reaches a speed of 39.6 m/s on a 30° ski slope. Ignoring friction, what was the minimum distance along the slope the skier would have had to travel, starting from rest?Select one:a.640 mb.160 mc.320 md.110 m

A skier is pulled by a towrope up a frictionless ski slope that makes an angle of 12° with the horizontal. The rope moves parallel to the slope with a constant speed of 1.0 m/s. The force of the rope does 900 J of work on the skier as the skier moves a distance of 8.0 m up the incline. (a) If the rope moved with a constant speed of 2.0 m/s, how much work would the force of the rope do on the skier as the skier moved a distance of 8.0 m up the incline? At what rate is the force of the rope doing work on the skier when the rope moves with a  speed of (b) 1.0 m/s and (c) 2.0 m/s?

A girl and her bicycle have a total mass of 40 kg. At the top of the hill her speed is 5.0 m/s. The hill is 10 m high and 100 m long. If the force of friction as she rides down the hill is 24 N, what is her speed at the bottom?Select one:a.10 m/sb.5.0 m/sc.11 m/sd.She stops before she reaches the bottom.

Consider the skier on a slope shown in Fig.2. Her mass including equipment is 70 kg.Calculate her acceleration if friction is known to be 45 N.
