Question

What is the mass of a rock on the edge of a 40m cliff with 980 joules of potential energy?

calculate a hammer's PEi with a KEi of 0J, a PEf of 10j, and a KEf of 185 J.


if a 2kg bowling balls PEi is 100j and KEi is 21J, what is its final potential energy if it strikes the pins traveling at 6m/s?



please show work with units

Answer 1

Calculate Potential Energy (PE) for the given mass (m), acceleration of gravity (g) and height (h) through gravitational potential energy Calculator
