Q1. An archer puts a 0.26 kg arrow to the bowstring. An average force of 213 N is exerted to draw the string back 1.3 m. unless otherwise directed, suppose that air resistance is negligible. Illustrate energy bar graphs to solve the problem.

(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. A simple harmonic oscillator consists of a block of mass 1.80 kg attached to a spring of spring constant 107 N/m. while t = 1.00 s, the position and velocity of the block are x = +0.129 m and v = +3.415 m/s.
