Q1. Suppose a small metal ball of mass and negative charge. The ball is released from rest at the point and constrained to move along the z axis, with no damping. If, what would be the ball's subsequent trajectory?
Q2. A rattlesnake can strike with the acceleration equivalent to an increase in speed from 0 to 60 mi/h in 1/2 s. If the rattlesnake's head weighs 0.33 lb, what average power does the rattlesnake generate throughout its strike?
