You and your friends are doing physics experiments on a frozen pond that serves as a frictionless, horizontal surface. Sam, with mass 76.0 kg, is given a push and slides eastward. Abigail, with mass 56.0 kg, is sent sliding northward. They collide, and after the collision Sam is moving at 32.0 ∘ north of east with a speed of 6.40 m/s and Abigail is moving at 22.0 ∘ south of east with a speed of 8.20 m/s. What was the speed of each person before the collision?
A. Sam's speed.
B. Abigail's speed.
C. By how much did the total kinetic energy of the two people decrease during the collision?

Read this excerpt from a room of one's own by virginia woolf: nick greene, i thought, remembering the story i had madeabout shakespeare's sister, said that a woman acting puthim in mind of a dog dancing. johnson repeated thephrase two hundred years later of women preaching. andhere, i said, opening a book about music, we have the verywords used again in this year of grace, 1928, of womenwho try to write music.
