Question

7. Three boxes are connected by strings that pass over massless, frictionless pulleys. The coefficient of kinetic friction involving the table is 0.13. The masses are m1 = 8kg, m2 = 50kg and m3 = 16kg. Which way will the objects move? What is their acceleration? What is the tension in each rope? If the box on the table starts at rest on one end, and the table is 1.5m across, how fast will it be going when it reaches the other end of the table (assume it had to slide the entire length of the table as it was pulled along)?

Two masses are connected by a string as shown below. The coefficient of kinetic friction between the table and the mass is 0.18 m1=1.5kg m2=3.5kg a) Draw and label the free body diagrams for each mass b) Determine the force of friction on m1. c) Determine the acceleration of the system d) Determine the tension in the string. e) If block 1 starts from rest, 0.55 m from the pulley, how much time will it take to reach the pulley?

Two blocks are connected by a massless rope as shown below. The mass of the block on the table is 4.3 kg and the hanging mass is 1.2 kg. The table and the pulley are frictionless. (a) Find the acceleration (in m/s^2) of the system. (Enter the magnitude.) (b) Find the tension (in N) in the rope. (c) Find the speed (in m/s) with which the hanging mass hits the floor if it starts from rest and is initially located 2.0 m from the floor.

00:01 Hello and welcome to this video solution of numerate.
00:04 So here we are given three boxes that are connected by strings and that pass over massless frictionless pulley, right? the coefficient of kinetic friction between the table is 0 .13.
00:18 The masses are m1 which is 8 kages m2 as 50 kages and m3 equal to 16 kages right now first you have to tell which way the object will move...
