Question

Consider the ramp shown in the diagram below. It is very similar to the one you used in lab with one difference. It does not have the horizontal section at the bottom of the incline.

(a) For the same value of h2 and for the first value of h1 that you used in the lab, which of the following is true for the velocity as the sphere leaves the ramp shown in the figure above?

a. There is no difference in the speed from that obtained in the lab.

b. The velocity will be horizontal and larger than the value obtained in the lab.    

c. The velocity will point vertically downward.

d. The velocity has a smaller horizontal component than the value obtained in the lab plus a non-zero vertical component.

e. The velocity will have the same horizontal value and no vertical component.

f. The velocity will be horizontal and smaller than the value obtained in the lab.

g. The velocity has a larger horizontal component than the value obtained in the lab plus a non-zero vertical component.

(b) Which of the four paths shown above will the sphere follow?

a

b    

c

d

(c) Consider the time of flight of the sphere once it leaves the ramp. How long will the sphere take to reach the ground in this case compared to that in the lab setup?

a. The sphere will take less time as it has a non-zero vertical velocity when it leaves the ramp.

b. Not enough information is provided to determine this.    

c. The sphere will take less time as it has a smaller horizontal velocity.

d. The sphere will take the same time because horizontal velocity does not change.

e. The sphere will take the same time because the value of h2 is the same.

f. The sphere will take more time because it has both horizontal and vertical velocity components.
