Q24 is poorly worded. It also confuses students unnecessarily because it asks for the ratio of initial to final energy instead of final to initial energy.
Q25 should say "The truck driver slams..." not "The truck drives slams..."
Q25 should also plainly state that the force is constant.
I corrected Q25 for the grammar. I don't think it's poorly worded though - I've seen problems that ask for the initial over the final ratio, and also the final over the initial. John
