However, it fails to make it over the hill, and eventually goes back down. If friction effects are negligible, then: A) What is the cart's initial kinetic energy? [J] a) +3.74x103 c) +9.35x103 COLXDL'E- (q d) -9.35x103 ) None/Zero B) What is the cart's initial potential energy? [J] a) +3.74x103 ) +9.35x103 b) -3.74x103 d) -9.35x103 e) None/Zero C) What is the work done by the normal force from the hill? [J] a) +9.35x103 c) +2.34x10* b) -9.35x103 d) -2.34x104 e) None/Zero D) What is the cart's kinetic energy just before it starts to go a) +9.35x103 c) +2.34x10* back down? [J] b) -9.35x103 d) -2.34x10* e) None/Zero E) What is the maximum height the cart reaches? [m] a) +5.56 c) +13.9 b) -5.56 d) -13.9 e) None/Zero
