Q1. An archer puts a 0.30 kg arrow to the bowstring. An average force of 201 N is exerted to draw the string back 1.3 m. unless otherwise directed, imagine that air resistance is negligible. Illustrate energy bar graphs to solve the difficulty.
(a) Assume that all the energy goes into the arrow, with what speed does the arrow leave the bow?
(b) If the arrow is shot straight up, how high does it rise?
Q2. Two point charges of magnitude 5.0 uC and -3.0 uC are separated by 35.0 cm. what is the potential difference between a point infinitely far away and a point midway between the charges?
