A 50 kg box hangs from a rope. What is the tension in the rope if
a. The box is at rest?
b. The box has vy = 5.0 m/s and is slowing down at 5.0 m/s2
?

1. net force of y is zero
a)
0 = T+ gravitation force
since we want to find Tension
T is unknown
and gravitation force is mass*gravity(-9.81)
0= T+ (50)(-9.81)
0=T-490.5
T=490.5N
