Final answer:
The acceleration parallel to the incline can be determined using a formula that takes into account the angle of the incline and the coefficient of friction. In this case, since the incline is frictionless, the acceleration is simply equal to g · sin θ.
Step-by-step explanation:
The acceleration parallel to the incline can be determined using the formula:
acceleration = g · sin θ - μ · g · cos θ
Where:
acceleration is the acceleration parallel to the incline
g is the acceleration due to gravity (approximately 9.8 m/s²)
θ is the angle of the incline
μ is the coefficient of friction
In this case, since the incline is frictionless, the coefficient of friction is 0. Therefore, the acceleration is simply equal to g · sin θ.
Using this formula, you can calculate the acceleration parallel to the incline when there is 45.0 N of opposing friction.
