my physics textbook is pretty pathetic. its too conceptual and lacks formulas. id reallly appreciate it if u could help me!! 
Q) a coaster ascends a 34.1 m hill and then drops 21.9 m before moving on to the next hill. The train of cars has a mass of 4727 kg.
a) how much work is required to get an empty train of cars from the ground to the top of the first hill?
b) what power must be generated to bring the train to the top of the first hill in 30 seconds?
c) how much PE is converted into KE from the top of the first hill to the bottom of the 21.9-m drop?
knock urselves out. i really am trying but whenever i think of a formula that would work, it seems as if the question is lacking information!!!
look, i know its long and intimidating. but im not asking u to legit solve it . just give me the steps of solving it or give me a hint that will help me figure out how to solve it. cuz giving me the answer does nothing for me.
