The net external force on the propeller of a
3.3 kg model airplane is 6.5 N forward.
What is the acceleration of the airplane?
Answer in units of m/s2.
Fnet = ma
6.5 = 3.3a
6.5/3.3 = a
1.97 = a
thank you!
To find the acceleration of the airplane, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
The formula for Newton's second law is:
F = m * a
Where:
F is the net force on the object
m is the mass of the object
a is the acceleration of the object
In this case, we are given that the net external force on the propeller is 6.5 N forward (positive direction), and the mass of the airplane is 3.3 kg. We need to find the acceleration.
Rearranging the formula, we have:
a = F / m
Plugging in the given values:
a = 6.5 N / 3.3 kg
Now, we can calculate the answer:
a ≈ 1.97 m/s²
Therefore, the acceleration of the airplane is approximately 1.97 m/s².
