Two weights are connected by a massless wire and pulled upward with a constant speed of 1.50 m/s by a vertical pull P. The tension in the wire is T (see figure). What is the value of T? Pull P 25 N Tension T 100 N 100 N 125 N 150 N 75 N

Step 1
Since the weights are being pulled upward with a constant speed, this means that the net force acting on them is zero (because there is no acceleration). The forces acting on the weights are the upward pull P, the upward tension T, and the downward force of Show more…
