1. A child falls sideways off a sled while sledding on friction-less ice. What
happens to the velocity of the sled? *

O b) It remains the same.
d) cannot be determined from the information given
c) It decreases.

Answer:

c) It decreases.

Explanation:

If you treat this as a case of momentum of the sled while sledding on a friction-less ice, then mass and velocity are directly proportional. This means increasing either mass or velocity , the momentum of the object increases proportionally.

In this question, when the child falls sideways off the sled, the mass reduces, the velocity experiences the same causing a decrease in momentum .
