Question

One can easily get off a frictionless horizontal surface by jumping.
a) True
b) False

Answer 1

False. One cannot easily get off a frictionless horizontal surface by jumping.

Step-by-step explanation:

False

One cannot easily get off a frictionless horizontal surface by jumping. In the absence of friction, there would be no force opposing the motion, which means that jumping would not result in any horizontal displacement. The person would simply remain in the same position and land back on the surface from which they jumped.

For example, imagine a person jumping on an ice rink. Since ice has very little friction, the person would not be able to move horizontally from their initial position by jumping alone.
