Two ice skaters have masses m1 and m2 and are initially stationary.Their skates are identical. They push against one another, as shownbelow, and move in opposite directions with different speeds. Whilethey are pushing against each other, any kinetic frictional forcesacting on their skates can be ignored. However, once the skatersseparate, kinetic frictional forces eventually bring them to ahalt. As they glide to a halt, the magnitudes of theiraccelerations are equal, and skater 1 glides 4 times as far asskater 2. What is the ratio m1 / m2 of their masses?

i need someone to show me how to work this and give me the correctanswer please

Two particles with charges q and 2q moving from west to eastenter a uniform magnetic ?eld of magnitude B pointing verticallydown. The charges have different masses, but the same speed v. Inthe magnetic ?eld, they move in semicircles with radii R and 2R,respectively.

(a) What is the ratio of their masses?
(b) Is it possible to apply an electric ?eld that would cause theparticle of charge q to move in a straight line in the magnetic?eld? If yes, what is the direction and magnitude of this?eld?
(c) What effect would this electric ?eld have on the particle ofcharge 2q?

Two boys are sliding toward each other on a frictionless, ice-covered parking lot. Jacob, mass 45.0 kg is gliding to the right at 8.00 m/s, and Ethan, mass 31.0 kg, is gliding to the left at 11.0 m/s along the same line. When they meet, they grab each other and hang on. (a) What is their velocity immediately thereafter? (b) What fraction of their original kinetic energy is mechanical energy after their collision? That was so much fun that the boys repeat their collision with the same original velocities, this time moving along parallel lines 1.20 m apart. At closest approach, they lock arms and start rotating about their common center of mass. (d) Find their angular speed. (e) What fraction of their original kinetic energy is still mechanical energy after they link arms? (f) Why are the answers to parts (b) and (e) so different?
