A cart of mass 8.0kg was moved by applying two constant forces. Force 1 is 28.0N at 42.0 degrees, and Force 2 is 13.0N at 110 degrees. Initially, the cart has a velocity of (3.50i + 2.20j)m/s. a. Express the two forces in unit-vector notation. b. Find the total force exerted on the cart. c. Find the angle at which the total force is applied. d. What is the acceleration of the cart? e. What is the cart's velocity after 5.0s? f. What is the position of the cart after 5.0s? g. What is the angle of the position after 5.0s? h. What is the total work done by the two applied forces?
