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. A.
Weight, gravity, and friction are acting on the person. The forces are unbalanced. Gravity is the strongest force causing the person to move.
B.
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.
C.
Gravity and air resistance are acting on the person. The forces are balanced until the person reaches the bottom of the water slide.
D.
Gravity and friction are acting on the person. The forces are unbalanced because the person is sliding down the slide.

the answer for apex is the lowest

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
