Question

You measure the mass of your rubber band airplane and find that it is 15 grams (0.015 kg). You also measure the acceleration of the airplane with a motion detector and find that the airplane initially accelerates upward at a rate of 2 m/s 2. Calculate the net force on the airplane and the upward force from the lift.

Answer 1

F=ma

Mass= 0.015 kg
Acceleration= 2 m/s^2

So force is equal to 0.015 * 2 = 0.03 N.
