I am supposed to write y to the 7/2 power without radical exponents...
that's the root of y to the 7th. I simplified it further and wrote y cubed root y. However, on the answer sheet it's simply written as root y to the 7th power.
Is this reducable or no?

A 33 g lead bullet initially at 20°C comes to rest in the block of a ballistic pendulum. Assume that half the initial kinetic energy of the bullet is converted into thermal energy within the bullet. If the speed of the bullet was 410 m/s, what is the temperature of the bullet immediately after coming to rest in the block?

The answer is 621.32 K or 350 degree C Please explain how to solve

Also, how do I solve for thermal energy by knowing the energy input, the heating up and vaporization of a known
amount of water. Is there a specific equation? I can't seem to find one, so any help will by very appreciated!
