AP Physics 1mediummcq1 pt

A 10 kg box on level ground has μ_s = 0.40 and μ_k = 0.25 (g = 10 m/s²). A horizontal 30 N push is applied. The box

A.stays at rest; static friction is 30 N

B.accelerates at 0.5 m/s²

C.moves at constant speed

D.accelerates at 3.0 m/s²

Explanation

Core Concept

30 N is below the 40 N maximum, so static friction matches the push and the box does not move.

Correct Answer

Astays at rest; static friction is 30 N
