Four students recorded the distance a plastic puck slid across a smooth ice surface after receiving an equal push force. They organized their trial results in the table below.
Which student statement is correct based on the evidence in Trial 1?
A Maya: "The smooth ice surface had zero friction because the puck slid a distance of 12 m, which was further than all other surfaces."
B Jayden: "The smooth ice surface has low friction, but it still has friction because the puck eventually stopped moving after sliding 12 m."
C Sofia: "The smooth ice surface has higher friction than the rubber mat because ice crystals push back against moving objects."
D Liam: "The smooth ice surface created zero friction while the puck was sliding, but created maximum friction right when it stopped."
B Jayden: "The smooth ice surface has low friction, but it still has friction because the puck eventually stopped moving after sliding 12 m."

Two identical toy trucks are lined up on a track. Truck A is empty, while Truck B is loaded with heavy metal blocks. If you give both trucks the exact same push, what will happen and why?
A Truck A will stop immediately because lighter objects cannot hold the force of a push very long.
B Truck A will move faster because a push has a greater effect on an object with less mass.
C Both trucks will move at the exact same rate because they both received the exact same push.
D Truck B will move faster because the extra mass gives the truck more energy to move forward.
B Truck A will move faster because a push has a greater effect on an object with less mass.
