"On an essentially frictionless, horizontal ice rink, a skater moving at 4.3 m/s encounters a rough patch that reduces her speed by 42% due to a friction force that is 24% of her weight. Use the work—energy theorem to find the length of this rough patch."

On an essentially frictionless horizontal ice-skating rink, a skater moving at 2.8 m/s encounters a rough patch that reduces her speed by 47 % to a friction force that is 22 % of her weight. Use the work-energy principle to find the length of the rough patch.

Part C Review A 4.5 kg box slides down a 5.2-m -high frictionless hill starting from rest, across a 2.3-m -wide horizontal surface then hits a horizontal spring with spring constant 470 N/m How far is the spring compressed? Express your answer using two significant figures The other end of the spring is anchored against a wall The ground under the spring is frictionless, but the 2.3-m- long horizontal surface is rough. The coefficient of kinetic friction of the box...

A 92.71 kg skater moving initially to the right at 0.39 m/s on rough horizontal ice comes to rest uniformly (constant acceleration) in 5.85 s due to friction from the ice. What force does friction exert on the skater?
A 60 kg skater is gliding across frictionless ice at 4.0 m/s
A 60 kg skater is gliding across frictionless ice at 4.0 m/s. Air resistance is not negligible. You can model the skater as a 170-cm-tall, 36-cm-diameter cylinder.Part AWhat is the skater's speed 6.0 s later?
