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 or incorrect?

1.)N equals Mg

2.)M will accelerate if T exceeds kN

3.)T equals sN if M remains at rest

4.)M will accelerate if T exceed sN

5.)If M does not accelerate, then T sN

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

Solution

1 True

2 False

3 False

4 True

5 False

6 False
