A cable is lifting a construction worker and a crate, as the drawing shows. The weights of the worker and crate are 918 and 1420 N, respectively. The acceleration of the cable is 0.620 m/s2, upward. What is the tension in the cable below the worker? What is the tension in the cable above the worker? I got this as my answer but it is incorrect.

Explanation / Answer

a. .tension below = 1420*(1+0.62/9.8)

= 1509.46 N

b. tension above = m(g+a)

= mg(1+a/g)

=(918+1420)(1+0.62/9.8)

= 2485.29 N
