A skier starts down a 14 ∘ incline at 2.0 m/s, reaching a speed of 15 m/s at the bottom. Friction between the snow and her freshly waxed skis is negligible. What is the length of the incline?

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j

What is a possible result of higher air temperature caused by global warming

Yvette hangs a 2.4kg bird feeder in the middle of a rope tied between two trees. the feeder creates a tension of 480 n in each side of the the rope.
