At time t = 0 s, a motor begins to move a small elevator of mass 117 kg by unreeling a cable. The position of the elevator as a function of time is given by y(t) = yie^(−t/t0) where yi = 87 m and t0 = 1.77 s and we have defined up to be the positive y direction. What is the tension in the elevator cable at time t = 3.26 s?

Question

At time t = 0 s, a motor begins to move a small elevator of mass 117 kg by unreeling a cable. The position of the
elevator as a function of time is given by
y(t) = yie^(−t/t0)
where yi = 87 m and t0 = 1.77 s and we have defined up to be the positive y direction. What is the tension in the
elevator cable at time t = 3.26 s?
