2. A man pushes a crate of mass 70kg along a horizontal floor with a constant horizontal force in an easterly direction. Starting from rest, the trunk reaches a velocity of 1.5 m/s (E) after 3.0 s. The coefficiant of Kinetic friction between the crate and the floor is 0.34. Determine the man's horizontal applied force. Be sure to draw a free body diagram and indicate positive direction.

Consider Figure 5.28. The driver attempts to get the car out of the mud by exerting a perpendicular force of 610.0 N, and the distance she pushes in the middle of the rope is 1.00 m while she stands 6.00 m away from the car on the left and 6.00 m away from the tree on the right. What is the tension Tin the rope, and how do you find the answer?

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)
