Question

A 45 kg crate is dragged 14 m using a rope. The rope is pulled with 180 N of force at a 30-degree angle, and there is a coefficient of friction μ = 0.3. The crate starts from rest. A. How much work is done by the person pulling the rope? B. How much work is done by friction? C. How much net work is done? D. What is the object's kinetic energy at the end of the 14 m? E. What is its velocity at the end of the 14 m?

Step 1

Given: Force applied = 180 N, angle = 30 degrees, displacement = 14 m Work done by the person = Force * displacement * cos(angle) Work done by the person = 180 N * 14 m * cos(30 degrees) Work done by the person = 2180 J Show more…
