Homework Statement
**please check diagram i have attached**i have a few problems all relevant to this information
a trolley with mass of 4kg moves without friction. initially the trolley is on AB and moving to the right with a velocity of 10ms. DE is 2m above AB and C is 5m below C
a) what is total energy of trolley at C? (is this the same as potential energy so would be 4*9.8*5? or would the formula be different?
b) if the potential energy of the trolley is 274.4 Joules determine its kinetic energy as it moves along DE..
im confused on how to change potential energy to kinetic energy in this situtation or is this a trick question? as it has potential energy it doesn't have kinetic energy so the answer is 0?
