3. [2pt] The following problem has several parts; e.g., if the answer to part (1) is A, to part (11), B, to part (111), ABCD, and the answer to the last two questions is t, enter ABABCD+- FL 1) Two forces are exerted on an object of mass m in x direction as indicated by the free body diagram. Assume these are the only forces acting on the object. Which of the curves on the graph below could be a plot of V (1), the velocity of the object in the x direction as a function of time? C 11) Consider again the FBD shown above (but not the graph). Which of the curves on the graph below could be a plot of x(t), the position of the object as a function of time? B с D 111) Below are top views of four identical objects moving to the right at 20 m/s. Various forces act on the objects in the horizontal plane, either parallel to the motion or at 45°, 90° or 135° Rank the objects on the basis of their speed just after the forces are applied, from largest to smallest, e.g., enter ABCD. 110 10 N 10 N 10 N 10 N 10 10N B) lov 10 A) 10 N 10 N C) #10 N D) For the following two situations, the positive y axis is upward. As your input enter an answer of either -; - or 0. iv) A man bungee jumps over the side of a bridge.
