Exercise 8.27
Part A
Two ice skaters, Daniel (mass 60.0 kg ) and Rebecca (mass 45.0 kg ), are
practicing. Daniel stops to tie his shoelace and, while at rest, is struck by
Rebecca, who is moving at 13.0 m/s before she collides with him. After the
collision, Rebecca has a velocity of magnitude 8.00 m/s at an angle of 55.1
from her initial direction. Both skaters move on the frictionless, horizontal surface
of the rink.
What is the magnitude of Daniel's velocity after the collision?

Solve it correctly please. I
Jill threw a dodgeball completely horizontal in x-direction with velocity of +5 m/s and mass of .5 kg. At the same time her friend threw a dodgeball with the same mass in the -x direction and a velocity of -2 m/s. The balls hit each other, and Jill's ball was deflected 30° above the original path, while her friend's deflected 20⁰. below the initial path. a. Ignoring gravity, solve the velocity of each ball after the collision, using a free body diagram. b. If both balls had a magnitude of 3 m/s, how much kinetic energy was "lost" during the collision?

You have been enjoying trying some of the things you learn in Dr. Shaw's class. You and your brother Jason are on the top of Lenoir Hall, and are dropping things on people to startle them. You drop a lunchbox, and note that the momentum of the lunchbox is conserved while it is falling. True False
