4) A box of mass 30 kg is being dragged from rest up a frictional ramp by a rope with tension 500 N. See diagram. The ramp has coefficients of static and kinetic friction of 0.5 and 0.3. respectively. (a) Calculate the net work done on the object if it moves 5m up the ramp. (b) At the end of 5 m, what is the box's velocity? (Do not use motion equations.) Rope Ramp 250 Box Skid hangin' out 5) Do problem 4a) over using unit vector notation. Make your x- axis and y-axis horizontal and vertical, respectively. 10) A mass is hung from a ceiling by a cable that is 2 m in length. The mass is swung around so that it travels in a horizontal circle. While swinging the cable makes 30" an angle of 30" with the vertical. Find the velocity of the mass in order to maintain the angle
