A bullet of mass m1 is fired with a speed v into the bob of a ballistic pendulum of mass m2. Find the maximum height h attained by the bob if the bullet passes through the bob and emerges with a speed v/3. (Use any variable or symbol stated above along with the following as necessary: g.) h = ? I also know that Momentum is conserved in the collision of the bullet with the bob and kinetic energy is transformed into gravitational potential energy as the bob swings up to its maximum height.

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
