The force shown in the force vs. time diagram in the figure below acts on a 1.0-kg object.

*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).

(b) Find the final velocity of the object if it is initially at rest.

(c) Find the final velocity of the object if it is initially moving along the *x*-axis with a velocity of −1.7 m/s
