The problem is this Calculate the change inpotential energy of a 79.8 kg man when he takes an elevator fromthe first floor to 29th floor, if the distance between floors is3.87 m.I usethe potencial energy formula: potencial energy= mgh but i keepgetting it wrong Calculate the change inpotential energy of a 79.8 kg man when he takes an elevator fromthe first floor to 29th floor, if the distance between floors is3.87 m.
I usethe potencial energy formula: potencial energy= mgh but i keepgetting it wrong
Explanation / Answer
PE=mgh and since there are 29 floors and the man starts on thefirst we have 29-1=28 floors then 28(3.87)=h, soPE=mgh=(9.8)(79.8)(3.87)(28)=8.47x104 J
