- Homework Statement
- Avdol lifted a 35 kg box at uniform velocity from the ground up to a height of 2.0m.
a) Jotaro commented Avdol did work. Polnareff says gravity did work. Who is correct? Explain?
b) If Avdol then accidentally dropped it. How much kinetic energy will there be right before it lands? Explain your reasoning. (2 marks)
- Relevant Equations
- Ek = 1/2 m v^2
For:
a) Avdol did the work because he is the force that is causing the displacement, right?
b) Is there another formula we would have to use? I am confused at how this would work out and what the answer would be.
