Question
An aeroplane's engines provide a force of 30,000 N as it accelerates down the runway. The mass of the aeroplane is 4000 kg. Work out the acceleration of this aeroplane.
Solution 1
To calculate the acceleration of the airplane, we can use Newton's second law of motion, which states that Force = mass x acceleration (F = ma).
Given in the problem, we have:
Force (F) = 30,000 N Mass (m) = 4000 kg
We need to find acceleration (a), so we rearrange the formula to solve for a:
a = F/m
Substituting the given values:
a = 30,000 N / 4000 kg = 7.5 m/s²
So, the acceleration of the airplane is 7.5 m/s².
Solution 2
To calculate the acceleration of the airplane, we can use Newton's second law of motion, which states that Force = mass x acceleration (F = ma).
Given in the problem, we have:
Force (F) = 30,000 N Mass (m) = 4000 kg
We need to find acceleration (a), so we rearrange the formula to solve for a:
a = F/m
Substituting the given values:
a = 30,000 N / 4000 kg = 7.5 m/s²
So, the acceleration of the airplane is 7.5 m/s².
