a 0.0780 kg lemming runs off a 5.36 m high cliff at 4.84 m/s. What is its potential and kinetic energy when it lands? Ive tried so many answers but cant seem to find the right ones for this problem, any help will be greatly appreciated!
KInetic energy= 1/2 m v^2 m =.0780 v = 4.84 m/s This is its INITIAL K.E.
Final K.E. will equal this value PLUS the initial POTENTIAL ENERGY (=mgh) which will be converted to K.E.
The FINAL Potential Energy will be ZERO as h = 0
