Two boxes with masses m1= -60.0 kg and m2= -30.0 kg are connected by a light string that passes over a light, frictionless pulley One box rests on a frictionless ramp that rises at 40.0° above the horizontal, and the system is released form rest. (a) Make a force (or free-body) diagram of each of the boxes and include the coordinate system used for each box. (b) Write down Newton's 2ad law for each box in each relevant direction. (c) What is the magnitude of the tension in the string, and the magnitude of the acceleration of the boxes?
A box of mass 74.5 kg that is initially at rest is pulled by a rope at an angle of 30.0⁰
from the horizontal along a floor with a kinetic coefficient of friction of 0.717. A
force of 769 N acts on the rope.
Draw a free-body diagram of the situation. In your free-body diagram, include all of
the involved forces resolved into the horizontal and vertical directions. Use your
free-body diagram to determine how long it will take for the box to be moved 21.5 m
horizontally.
