The superheroine Xanaxa, who has a mass of 66.7 kg, is pursuing the 79.7 kgkg archvillain Lexlax. She leaps from the ground to the top of a 177 m high building then dives off it and comes to rest at the bottom of a 16.3 m deep excavation where she finds Lexlax and neutralizes him. By how much will gravitational potential energy change? Answer with a positive number. Assume ?=9.81 m/s^2

A toy gun fires a 9.41 g projectile disc by using a compressed spring (k= 1720 N/m). The barrel of the gun is 13.1cm (this is measured after the spring). As soon as the projectile goes leaves the spring, it creates thermal energy due to friction. The frictional force is 0.130N. If you compress the spring 14.0mm, what is the speed of the projectile when it leaves the gun?
