a ball rolls off of a desk that is 0.97m off of the ground and strikes the floor 0.76m away from the desk. how far was it rolling before to falling off of the desk? (acceleration of gravity is 9.81)

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.
