Problem 57P

CP? Boxes A and B are connected to each end of a light vertical rope (?Fig. P4.49?). A constant upward force F = 80.0 N is applied to box A. Starting from rest, box B descends 12.0 m in 4.00 s. The tension in the rope connecting the two boxes is 36.0 N. What are the masses of (a) box B , (b) box A?

Step-by-Step Solution:

Solution 57P Step 1: The forces on block B are, the upward tension force, the weight, and the force due to it’s downward acceleration. So, the equation will be like, m B T = m aB-------------(1) 2 The acceleration of block b is 12/4 = 3 m/s . The tension in the string is 36 N. So, the mass of block B will be, m = T = 36 = 36 =...
