John wants to move a 200-kg rock using a stiff bar measuring 3 meters long as a lever. he puts the fulcrum x meters from the rock. assume that g = 10m/s^2. 2-1. sketch this in a diagram and annotate the forces/velocities. (10pts) 2-2. if x = 0.5m, how much force must he use in order to move the rock? (10pts) 2-3. if the maximum force he can exert on the crowbar is 500n, what is
