Question

A worker drags a 150 -lb crate across a floor by pulling on a rope inclined $17^{\circ}$ above the horizontal. The coefficient of static friction is $0.52$ and the coefficient of kinetic friction is 0.35. (a) What tension in the rope is required to start the crate moving? (b) What is the initial acceleration of the crate?

Step 1

52, the weight of the crate is 150 lbs, and the angle theta is 17 degrees. The force required to move the crate can be calculated using the formula: \[ F = \text{Coefficient of static friction} \times \text{Weight} \times \cos(\theta) + \text{Coefficient of static Show more…
