Statement I: For a block held on a rough incline by friction, the easiest way to start it moving is to push it sideways along the surface of the incline.
Statement II: Pushing the block straight up the incline must overcome both the downhill component of gravity and the friction, while a sideways push fights friction alone.
Options:
Answer:
A
Solution:
Along the contour of the plane the gravity component does no work against the push, so only friction resists;
pushing up the plane adds the component to the resistance.
Both statements are true.
Option A.
