(a) An elevator of mass m moving upward has two forces acting on it: the upward force of tension in the cable and the downward force due to gravity. When the elevator is accelerating upward, which is greater, T or w? 1. T 2. w 3. Both forces are equal. (b) When the elevator is moving at a constant velocity upward, which is greater, T or w? 1. T 2. w 3.Both forces are equal. (c) When the elevator is moving upward, but the acceleration is downward, which is greater, T or w? 1. T 2. w 3.Both forces are equal.
Please help me on questions A - F
(a) An elevator of mass m moving upward has two forces acting on it: the upward force of tension in the cable and the downward force due to gravity. When the elevator is accelerating upward, which is greater, T or w?
(b) When the elevator is moving at a constant velocity upward, which is greater, T or w?
(c) When the elevator is moving upward, but the acceleration is downward, which is greater, T or w?
(d) Let the elevator have a mass of 1,225 kg and an upward acceleration of 2.3 m/s2. Find T.
