Question

A small engine causes a 0.30 kg model airplane to accelerate at a rate of 11 m/s2. What is the net force on the model airplane?

Answer 1

Answer : F = 3.3 N

Explanation :

It is given that :

Mass of model airplane, m = 0.3 kg

Acceleration,
`a=11\ m/s^2`

According to Newton's second law :

Force acting on an object is the product of mass and the acceleration with which it is moving.

F = m a

So,
`F=0.3\ kg* 11\ m/s^2`

`F=3.3\ N`

So, the net force on the model airplane is 3.3 N.
