Question

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.

Answer 1

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

Step-by-step 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.
