2) A nerf gun (spring constant 36 N/m) compresses by 0.23 m to fire a 0.045 kg foam dart.
If the dart is traveling at 6.1 m/s as it leaves the nerf gun, was energy conserved? Briefly,
explain your thinking.
3) After falling 18 m, a 0.057 kg tennis ball has a speed of 12 m/s (the ball's initial speed is
zero). Determine the average resistive force of the air in opposing the ball's motion.
