Answer:
The graph between the static force and the x component of the pulling force is given as indicated in the figure.
Explanation:
The graph between the static force and the x component of the pulling force is given as indicated in the figure. The point of minimum force is also identified on the graph to indicate the minimum force required to overcome the static friction and accelerate the crate.
Answer:
82.62%
Explanation:
The z score is a score used in statistics to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
From the normal distribution table, P(11.85 < x < 12.15) = P(-1.36 < z < 1.36) = P(z < 1.36) - P(z < -1.36) = 0.9131-0.0869 = 0.8262 = 82.62%
