An elevator is accelerating upward at a rate of 3.8 m/s2. A block of mass 24 kg hangs by a low-mass rope from the ceiling, and another block of mass 63 kg hangs by a low-mass rope from the upper block.
(a) What are the tensions in the upper and lower ropes?
upper rope N
lower rope N
(b) What are the tensions in the upper and lower ropes when the elevator accelerates downward at a rate of 3.8 m/s2?
upper rope N
lower rope N
