Answer:
Newton's second law
Newton's second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration a of its centre of mass, F = ma, is the basic equation of motion in classical mechanics.
Explanation:
Answer:
B) μ = 0.23
Explanation:
The coefficient of friction is equal to μ = F / N where μ (mu) is the coefficient of friction, F is the friction force, and N is the normal force (the force of an object being applied onto the earth by gravity).
F, the friction force, is given as 67 N
Since the weight of the crate is 289 N, that means the normal force is 289 N.
This means that the coefficient of friction is μ = F / N = 67 N / 289 N = 0.23183391 = 0.23
Therefore, B is the correct answer
