AFCI Question 8 through 11

Use the following animations to answer questions 8 through 11

The animations depicts a hockey puck sliding with constant velocity v0 in a straight line from point "a" to point "b" on a frictionless horizontal surface. Forces exerted by the air are negligible. You are looking down on the puck. When the puck reaches point "b", it receives a swift horizontal kick in the direction of the black arrow. Had the puck been at rest at point "b", then the kick would have sent the puck in horizontal motion with a speed vk in the direction of the kick.

AFCI Question 8

Which animation shows the path the puck would mostly closely follow after receiving the "kick"?

Animation A
Animation B
Animation C
Animation D
Animation E

AFCI Question 9

What is the speed of the puck just after it recieves the kick?

equal to the speed "v₀" before it recieved the kick.
equal to the speed "v_k" resulting from the kick and independant from speed "v₀".
equal to the arithmetic sum of the speeds "v₀" and "v_k".
smaller than either of the speeds "v₀" or "v_k".
greater that either of the speeds "v₀" or "v_k" but less than the arithmetic sum of the two speeds

AFCI Question 10

Along the frictionless path you have chosen in question 8, the speed of the puck after receiving the kick:

is constant.
constantly increases.
constalnly decreases.
increases for a while and decreases thereafter.
is constant for a while and decreases thereafter.

AFCI Question 11

Along the frictionless path you have chosen in question 8, the main force(s) acting on the puck after reciving the kick is/are:

a downward force of gravity.
a downward force of gravity and a horizontal force in the direction of the motion.
a downward force of gravity, an upward force exerted by the surface, and a horizontal force in the direction of motion.
a downward force of gravity and an upward force exerted by the surface.
none. (No forces act on the puck.)
