Question

A seal slides down a ramp with an acceleration of 1.26 m/s2.

Find the coefficient of kinetic friction between the seal and the
ramp if the slide is inclined at an angle of 33.00 below the
horizontal.

Answer 1

The coefficient of kinetic friction between the seal and the ramp can be found using the formula μk = a / (g · cos(θ)). Substituting the values given in the question, the coefficient of kinetic friction is approximately 0.151.

Step-by-step explanation:

The coefficient of kinetic friction can be found using the formula:

μk = a / (g · cos(θ))

Where:

• μk is the coefficient of kinetic friction
• a is the acceleration of the seal
• g is the acceleration due to gravity (approximately 9.8 m/s2)
• θ is the angle of incline (33°)

Using the given information, we can substitute the values into the formula:

μk = 1.26 / (9.8 · cos(33°))

Simplifying the equation, we have:

μk ≈ 0.151

Therefore, the coefficient of kinetic friction between the seal and the ramp is approximately 0.151.
