The amount of force the weightlifter used to raise the barbell is 600N
From the question,
We are to determine the amount of force the weightlifter used to raise the barbell
From Newton's second law of motion,
The force acting on an object is equal to the mass of that object times its acceleration
That is,
F = ma
Where
F is the force
m is the mass
and a is the acceleration
From the question
m = 200 kg
a = 3 m/s²
Putting the parameters into the equation, we get
F = 200 × 3
F = 600N
Hence, the amount of force the weightlifter used to raise the barbell is 600N
