A 2.00 kg box is suspended from the end of a light vertical rope. A time-dependent force is applied to the upper end of the rope, and the box moves upward with a velocity magnitude that varies in time according to v1t2 = (2.00 m/s2)t +(0.600 m/s3)t2. What is the tension in the rope when the velocity of the box is 9.00 m/s?

Question

A 2.00 kg box is suspended from the end of a
light vertical rope. A time-dependent force is applied to the upper
end of the rope, and the box moves upward with a velocity magnitude
that varies in time according to v1t2 = (2.00 m/s2)t +(0.600 m/s3)t2.
What is the tension in the rope when the velocity of the box is
9.00 m/s?
