Jim Master attempts to lift a 100 kg barbell, but his strength fails. If the net force is 400N, identify the dominant force
the magnitude and direction of the acceleration.
Tension, 4 m/s/s upward
Tension, 9.8 m/s/s upward
Gravity, 4 m/s/s/ downward
Gravity. 9.8 m/s/s downward
a) In this system the only force is the gravitational force, acting as a centripetal force.
b) In this system, the acting force is the friction force, inward.
c) In this system, only tension and gravity act as forces
d) In this system, only the normal force inside the dryer acts.
