A. Computing the velocity using the Law of Conservation of Energy 1. Set the following variables: mass of Trevor, m =120 kg, and spring constant, k = 950N/m. 2. Click "Set Trevor". Pull Trevor back to compress the spring to 0.8m. 3. Fire Trevor and start to time his motion in the neutral zone (zone from blue line to blue line). 4. Record the distance traveled in the neutral zone (distance from blue line to blue line). 5. Compute for the velocity of Trevor in the neutral zone using vc= |Ax/ At| 6. Compare your computed velocity to the velocity acquired from the energy transformation equation Ko+ Uelo= Kf+ Uelf.
