Question

@Abhisar A system has 410 J of potential energy and 80 J of kinetic energy. Then 90 J of the potential energy is converted into kinetic energy. How much work was done on the system?

170 J
90 J
490 J
330 J

Answer 1

I think its 90 or 170

Answer 2

It should be 90J

Answer 3

This potential energy gets converted into KE and thus work is done.

Answer 4

Thanks
