consider a person sliding down a water slide at constant velocity. what are the forces acting on the person as they slide? determine if the forces are balanced or unbalanced. explain.\na gravity and friction are acting on the person. the forces are unbalanced because the person is sliding down the slide.\nb gravity and air resistance are acting on the person. the forces are balanced until the person reaches the bottom of the water slide.\nc weight, gravity, and friction are acting on the person. the forces are unbalanced. gravity is the strongest force causing the person to move.\nd gravity and friction are acting on the person. the forces are balanced. there is no net force because the person is moving at a constant velocity.

Answer

Brief Explanations:

According to Newton's first - law, an object moving at a constant velocity has no net force acting on it. When a person is sliding down a water - slide at a constant velocity, the force of gravity pulling the person down the slide is balanced by the frictional force (and possibly some small air resistance, but friction is the main opposing force here) acting in the opposite direction. Weight is the force due to gravity, so it's not an additional separate force from gravity in this context.

Answer:

D. Gravity and friction are acting on the person. The forces are balanced. There is no net force because the person is moving at a constant velocity.
