The force shown in the force vs. time diagram in the figure below acts on a 1.4-kg object. A coordinate plane has a horizontal axis labeled t (s) and a vertical axis labeled F_x (N). A straight line is drawn from (0,2) to (3,2), then from (3,2) to (5,0). A vertical dashed line is drawn from (3,0) to (3,2).

(a) Find the impulse of the force. __________N · s
(b) Find the final velocity of the object if it is initially at rest. __________ m/s
(c) Find the final velocity of the object if it is initially moving along the x-axis with a velocity of −1.5 m/s. _______ m/s
