Question

1. which of the following is an example of newtons 3rd law? * a. a full grocery cart requires more force to push than an empty cart b. pushing backward in order to move forward while ice skating c. a cookie sitting on a plate d. none of the above 10 points

Explanation:

Newton's 3rd Law states that for every action, there is an equal and opposite reaction. Pushing backward while ice - skating causes a forward motion as the reaction to the backward - pushing action force. Option A is about Newton's 2nd Law (F = ma, more mass requires more force). Option C is just an object at rest and has no action - reaction pair shown.

Answer:

B. Pushing backward in order to move forward while ice skating
