Resposta
To find the coefficient of kinetic friction, we can use the equation:
Given:- Angle of the incline,
- Acceleration,
- Acceleration due to gravity,
Substitute the given values into the equation:
Simplify the equation:
Since the coefficient of kinetic friction cannot be negative, there must be an error in the given acceleration value. Therefore, the correct answer is:c) Cannot be determined from the information given
