![**Question 15**
A 57-kg packing crate is pulled with constant speed across a rough floor with a rope that is at an angle of 41° above the horizontal.
**Part A**
If the tension in the rope is 192 N, how much work is done on the crate by the rope to move it 8.1 m?

**Explanation**
This problem involves calculating the work done on a crate being pulled at an angle. The key factors are:
- **Mass of the crate:** 57 kg
- **Tension in the rope:** 192 N
- **Angle of the rope:** 41° above the horizontal
- **Distance moved:** 8.1 m
To solve this, you would use the formula for work done \( W \) by a force applied at an angle:
\[ W = F \cdot d \cdot \cos(\theta) \]
Where:
- \( F \) is the force applied (192 N)
- \( d \) is the distance the object is moved (8.1 m)
- \( \theta \) is the angle of the force from the horizontal (41°)
The answer should be expressed in joules (J) with two significant figures.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbe2dc1e3-fb5c-4361-9a35-12adea7e457d%2F66898773-b592-4181-a1c1-a582b4a8b809%2F6gk7y9q_processed.png&w=3840&q=75)
