A 10 N net force is applied to an object, which then accelerates at 4 m/s2. What is the mass of the object?
To find the mass of an object, we can use Newton's second law of motion, which states that the force applied to an object is equal to the mass of the object multiplied by its acceleration.
The formula for Newton's second law is:
F = m * a
Where:
F = force applied to the object (in Newtons)
m = mass of the object (in kilograms)
a = acceleration of the object (in meters per second squared)
Given:
F = 10 N
a = 4 m/s^2
To find the mass (m), we rearrange the formula:
m = F / a
Substituting the given values:
m = 10 N / 4 m/s^2
m = 2.5 kg
Therefore, the mass of the object is 2.5 kilograms.
To determine the mass of the object, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass.
The formula for Newton's second law is:
F = m * a
Where:
F is the net force applied to the object,
m is the mass of the object,
and a is the acceleration of the object.
From the given information, we know that the net force applied to the object is 10 N, and the acceleration of the object is 4 m/s^2.
To find the mass, we rearrange the formula and solve for m:
m = F / a
Substituting the values we have:
m = 10 N / 4 m/s^2
m = 2.5 kg
Therefore, the mass of the object is 2.5 kilograms.
