Q1. A bullet (1 g) is shot into a pendulum mass while it is hanging straight down (0.8kg). Just before impact with the pendulum, the bullet has speed 600m/s. The bullet-pendulum combination then swings together in a circular arc to a maximum angle of 0.2 rad. Find the speed of the bullet-pendulum combination right after the bullet becomes embedded (you can assume that this happens quickly enough that the combination has not yet had a chance to rise). What...

A cat's crinkle ball toy of mass 35 g is thrown straight up with an initial speed of 7 m/s. Assume in this problem that air drag is negligible. (a) What is the kinetic energy of the ball (in J) as it leaves the hand? (b) How much work is done (in J) by the gravitational force during the ball's rise to its peak? (c) What is the change in the gravitational potential energy of the ball (in J) during...
