Refer to the diagram shown below.
W = 87.5 N, the weight of the sandwiched board.
μ = 0.622, the static coefficient of friction.
From the free body diagram of the sandwiched board, obtain
2μF = W
F = W/(2μ) = 87.5/(2*0.622) = 70.34 N
Answer: 70.34 N

16.33m
Explanation:
Given parameters:
Mass of the hiker = 75kg
Potential energy = 12000J
Unknown:
Height = ?
Solution:
The potential energy is the energy at rest of a body.
Potential energy = mgh
m is the mass of the hiker
g is the acceleration due to gravity
h is the height
The unknown is the height;
Height =
Height = = 16.33m
