Two students are balancing on a 10 m seesaw . the seesaw is designed so that each side of the seesaw is 5 m long. the student on the left weighs 60 kg and is sitting three meters away from from the fulcrum at the center. the student on the right weighs 45 kg. the seesaw is parallel to the ground. the Mass of the board is evenly distributed so that is center of mass is over the fulcrum. imagine that two students are sitting on the seesaw so that the torque is 0 N*m. which of the following changes will alter the torque of the seesaw? a. another student stands perfectly on the center of the seesaw.
b. both students move toward the center by one meter.
c. the heavier student moves forward 1 m, while the lighter student moves forward 1.33 m.

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.
