A skateboarder travels on a horizontal surface with an initial velocity of 4.0 m/s m / s toward the south and a constant acceleration of 2.5 m/s2 m / s 2 toward the east. Let the x x direction be eastward and the y y direction be northward, and let the skateboarder be at the origin at t=0 t = 0 .

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.
