If an airplane's thrust is 235 mph and the wind's drag is 300 mph, would the plane have enough net force to fly?*
A. Yes, the net force is 65 mph thrust.
B. No, the net force is 65 mph drag.
C.. Yes, the net force is 535 mph thrust.
D. No, the net force is 535 mph drag.

B. No, the net force is 65 mph drag.

Explanation:

The thrust speed is given by 235 mph

The wind's drag is given as 300 mph

Now, drag is the opposite of thrust as it opposes the motion of the plane.

Excess force = thrust - drag = 235 - 300 = -65 mph

Since it's negative, it means the plane wouldn't move forward as the resisting speed is more than the thrust speed.

Thus, the plane wouldn't have enough to fly because there is a net force of 65 mph drag.

where is the photo and the answer choices?

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
