Q1) Mass 1 is moving at 2 m/s in the +x direction and it collides inelastically with mass 2 of 17 kg moving at 11 m/s in the + x direction. 122 Joules of KE is lost in this collision. What is the average force on mass 1 if the collision takes place in 0.1 seconds? Answer in Newtons.

Q2) A disk is initially spinning at 18 counter-clockwise. After 5 seconds, it is spinning clockwise and a piece of dust located 1 meter from the center of disk is moving at 9 m/s. How many revolutions does the disk make before it stopped spinning?
