Calculate the final speed of a 2.00-kg object that is pushed for 16.0 m by a 45.0‑N force directed 30.0∘ below the horizontal on a level, frictionless floor, as shown in the figure. Assume the object starts from rest.

When considering gravity acceleration and the force of acceleration, what must be true? a. the direction of acceleration must be perpendicular to the direction of the force. b. the direction of the force and the direction of acceleration must be the same as each other. c. the direction of the force and the direction of acceleration must be opposite of each other. d. the mass of the body must be the same as the acceleration of the body.
