Standing a few meters from a skateboard, a boarder begins running and then jumps onto the board. Make bar diagrams like the ones in Figure 7.32 to illustrate the energy conversions \((a)\) while he accelerates and \((b)\) while he jumps onto the board. Are the interactions dissipative or nondissipative?
