Question

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). Which one of the following relationships between T and P must be true? Pull P 25 N Tension T 100 N P = T + 100 N T=P P +T =125 N P=T +25 N Cannot be determined

Step 1

This implies that the net force acting on the system is zero because the acceleration (a) is zero (since speed is constant). Therefore, the upward force must balance the downward force due to gravity. Show more…
