student tries to help some local kids make a tire swing by throwing a rope over a branch, which is difficult because there are two branches (they should pick a different tree). The lower branch is c = 7 m off the ground and upper is d = 1m above that. The student throws the weighted end of a very light rope with an initial angle of 9 = 70° releasing it underhand at a = 0.5 m from the ground while standing b = 6 m from the tree. A %3D Determine the rauge of minimum and maximum initial velocities required to get over the lowest lin:b (B) without hitting the upper branch (C).
