Question

plzzz answer the questions it's urgent ...​

Answer 1

Explanation:

a) Friction opposes the motion. If man is trying to push the box to East, means, friction is acting towards west.

b) i) As the box doesnt move, means, man is unable to give that much force which can oppose the friction force. Concludes, friction force > force by man

→ friction force > 25 N

ii) As the box is at rest under friction force, box is experiencing static friction.
