## Homework Statement

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

A) N equals Mg

B) If M does not accelerate, then T less than or equal mu_s N

C) M will accelerate if T exceed mu_s N

D) M will accelerate if T exceeds mu_k N

E) T equals mu_s N if M remains at rest

F) The NET force on M (if M does not move) is T
