An exploder piston is set to maximum compression on the dynamics cart shown in Figure 6. The cart's mass is 0.88 kg. The spring constant of the piston is 36 N/m. Just after the piston is activated by the trigger on the cart, a motion sensor determines that the speed of the cart leaving the wall is 0.22 m/s. The cart rolls along the horizontal surface, coming to rest in 2.5 m. a)Determinethemaximumelastic potentialenergy in thespringand themaximumkinetic energyofthecart after it starts moving.What happenedtothe remaining elastic potential energy?
