Question

A cat with a mass of 4.50 kilograms sits on a ledge 0.800 meters above the ground. If it jumps to the ground, how much kinetic energy will it have just as it reaches the ground?    35.3 J 3.60 J 0.350 J cannot be determined

anonymous · Answer

KE= 0.5 x mass x velocity^2 
GPE = m x g x h 
GPE = KE 
4.5 x 0.8 x 9.81 = 35.316 J 
Answer is  0.350 J 

0.00100 x 0.5 x 2.2^2 = 2.42 x 10^-3 J

the first answer you wrote was correct,  4.5 x 0.8 x 9.81 = 35.316 J  

it seems like you copied and pasted from somewhere lol
