A bullet fired horizontally hits and gets embedded in the edge of a disk free to rotate about its vertical axis. The disk has a mass of 2.4 kg and radius 0.7 m. If the bullet of mass 13.7 g was moving with speed of 377.8 m/s find the angular speed in rad/s the disk-bullet gain after wards.

What happens to light waves from a star as the star moves away from earth?

Choose the most likely outcome of this scenario: jen decided to go bike riding without a helmet. while no one is around during her ride, she is thrown from her bike when her wheel goes into a pothole. she is not injured, but she is terrified to get back on her bike. what happens next? a. her physical health is affected even though she wasn't hurt. b. her mental and emotional health are affected because she is afraid to get back on her bike. c. her social health is affected because she is worried her friends saw the fall. d. her overall health is not affected at all by her fall.

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)
