Question

A mass M is initially at rest on a horizontal surface, ?s=0.30 and ?k=0.20 . A horizontal string then pulls M with a tension T. Forces below are magnitudes.

Correct Incorrect N equals Mg
Correct Incorrect M will accelerate if T exceeds ?kN
Correct Incorrect T equals ?sN if M remains at rest
Correct Incorrect The NET force on M (if M does not move) is T
Correct Incorrect M will accelerate if T exceed ?sN
Correct Incorrect If M does not accelerate, then T ? ?sN





Incorrect.
