Chapter 5 HW – Conservation of Energy… and Springs
... 15. A sling shot, which uses an elastic band to propel and object, has an elastic constant of 40 N/m. If a metal ball with a mass of 200g is pulled back 10 cm, a) how fast will it be moving when it leaves the sling shot? b) If the sling shot is held 1.5 m above the ground, what will its velocity be ...

... Note that the vertical forces balance but the horizontal forces do not. The net force is Fnet = 129.9 N, right - 60 N, left = 69.9 N, right The mass is m = (Fgrav / g) = 20 kg So the acceleration is a = (69.9 N) / (20 kg) =3.50 m/s/s. ...

Simple Harmonic Motion and Elastic Energy
... In mechanical systems, energy can be stored in springs. For example a compressed spring on a popgun can provide energy to a pellet and shoot it from the gun. Even a simple slingshot uses the elastic energy stored in a rubber band to shoot it projectile. When two balls collide it is as if a spring is ...
