1. Myrtle the Kitten loves anything that sparkles. She has stolen one of Dr. Woodney’s earrings ( mass = 20 g) off the dresser and is playing with it by batting it around on the tile floor of the house. If immediately after Myrtle hits the earring it is traveling across the kitchen floor at 5 m/s, and 3 s later it is traveling at 2 m/s across the floor: a. What is the coefficient of kinetic friction, μk between the earring and the floor? b. If you tripled the mass of the earring, what would the speed of the earring be after it traveled 4 m if it had the same initial velocity?

All problems must include: a sketch, a freebody diagram (or more than one if necessary), and a list of knowns and unknowns for full credit. A large pack of snow of mass m sits at the top of a trail at a ski resort. Friction keeps the snow pack in place, but when it starts to get hotter out the coefficient of friction changes and the snow will slide down the mountain in an avalanche. If the slope of the...

Captain Marvel is at rest in deep space (far enough from any star that any gravitational forces are negligable), enjoying the view of a distant nebula. Her mass is 85 kg. She applies 1500 kN of force to herself with her energy beams for 30 s, and then coasts for 5000 km. a. What...
