I Find the components of the vertical force F = (D, 15) in the directions parallel to and normal to the plane that makes an angle of E with The positive xaxis. Show that the total force is the sum of the two component forces. What is the component oi the force parallel to the plane? DID What is the component oi the force perpendicular to the plane? {31} Find the sum of these two forces. il-ii A suitcase is pulled 21] feet along a at sidewalk with a constant upward force of 80 lb at an angle of 23a with the horizontal. Calculate the work done. {:3 The work done is D lootpounds. (Round to the nearest foot-pound as needed.)
