- A 16-year-old employee working for Southern Virginia College's (SVC) bookstore during the summer months is helping prepare for Fall salesIt's a good way to make extra money, and the teen is saving for a car. Books from one supplier are shipped to the SVC bookstore in large crates equipped with rope handles on all sides. On one occasion, the teen momentarily pulled with a force of 669 N at an angle of 35.3above the horizontal to accelerate a 124-kg crate of books. The coefficient of friction between the crates and the vinyl floor is 0.588. Determine the acceleration experienced by the crate in m / (s ^ 2) Use the approximation g = 10; m / (s ^ 2)Asope is strung between tuo alls parallel 0the flori A 35 Ka mass is Ahe rope at it's midpoint.

What is the maximum force of friction (in N) under such conditions? (The frictional forces in joints are relatively small in all circumstances except when the joints deteriorate, such as from injury or arthritis. Increased frictional forces can cause further damage and pain.) 105823.34 X NConsider the figure below. (a) Find the tension in each cable supporting the 640-N cat burglar.
