Question

Required Solution Format

1. Understand the problem and devise a plan:

a. Read and translate the problem statement.

b. Determine applicable concepts and/or laws and assumptions and/or simplifications.

2. Represent the problem physically and mathematically.

a. Represent physically.

b. Represent the concepts and/or laws mathematically.

3.Solve for the unknown quantity (or quantities).

a.Solve for the unknown quantity (or quantities) using algebra, geometry, trigonometry and/or calculus.

4. Reflect. Is the answer reasonable? Does it make physical sense?

a. Evaluate the result (Is the answer reasonable? Are the units correct?).

1) You slide down a water slide that makes an angle θ with the horizontal, starting from rest. Determine the height of the slide h given that your final speed is v_f. The height h will be expressed in terms of θ, v_f, μ_k, and/or g. For the physical representation (part 2a), draw and label an appropriate free-body diagram. As part of the reflection (part 4a), use θ = 55.0°, v_f= 11.0 m/s, and μ_k = 0.0500 to see if the symbolic expression gives a reasonable answer.

Answer 1

Yes, the answer seems reasonable
