HELP WORTH 2O POINTS As kids sled down a hill: (highlight the correct answer for each) a. As the kids go down the hill, their potential energy (increases, decreases, or stays the same).
b. As the kids go down the hill, their kinetic energy will (increases, decreases, or stays the same).
c. As the kids go down the hill, their total energy (PE + KE) will (increase, decrease, or stay the same).
d. If the mass of the sled doubles (a 2nd kid jumps on!), then PE will (increase, decrease, or stay the same).
e. If the kids go down a hill double the height, the PE will (increase, decrease, or stay the same).
f. If the hill is icy and the sled doubles the velocity (faster mom!), the KE will (increase, decrease, or stay the same).
g. If the mass of the sled is half the size (or 1 kid is on it instead of 2!), the KE will (increase, decrease, or stay the same).

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
