In attempting to push an airplane, a person uses a force of 300 N. But the airplane does not move. The force of static friction that the floor exerts on the airplane must be: 300 N and opposite in direction to the applied force. Greater than 300 N and opposite in direction to the applied force. Less than 300 N and opposite in direction to the applied force. Less than 300 N and in the same direction as the applied force. Question 15 (Mandatory) (1 point) Newton's 2nd law can be written as: OFnet = m / a. OFnet = a / m. Oa = Fnet / m. Om = Fnet * a
