At most, a rope can pull an object with a mass of 3M and decelerate with a uniform acceleration If a rope can pull an object with a mass of 3M at most and decelerate at the acceleration of a, then the rope can pull an object with a mass of m at most and increase at the same speed?
From the problem, we know that the object rising at a constant speed is to find the maximum tension of the rope, and the weight of the object is the tension of the rope
On the first two conditional expressions
3mg-f = 3mA (uniform acceleration)
F-mg = ma (uniform deceleration)
Simultaneously, the tension of rope can be calculated as F = 3mA and g = 2A
5 mg
So we can pull an object with a mass of 1.5m to rise at a constant speed
