Mr. Maple is halfway down to the ground from his initial upright position before he starts to respond and tries to stop his descent (remember his initial height was 1.2m). If Mr. Maple wants to avoid falling any further than three-quarters of the way to the ground (i. e., stopping his downward motion three-quarters of the way down from his initial upright position) how much work must he do to stop his fall three-quarters of the distance from his initial upright position to the floor

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?

The mantle is made up of which structural zones?

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
