Need help with this Question ( Use image below) Solve correctly for an Upvote round to 3 sig figs and Circle final answer with correct units
Remember F = 280N
![**Description of Problem**
A 49-pound crate is accelerated from rest to a speed of 11 feet per second over a 4-second interval. The acceleration is constant throughout this time. The motor used for this task has an efficiency of 0.65. The mass of the pulley and cable is negligible. Refer to the diagram in Figure 1.
**Diagram Explanation (Figure 1)**
The diagram depicts a pulley system with a motor labeled "M" at the top. A cable runs over the pulley, connected to a crate. The crate is marked with a variable "s," indicating its motion in the vertical direction. The setup suggests vertical motion influenced by the motor's force transmitted through the pulley system.
**Part A**
Determine the power that must be supplied to the motor at \( t = 2 \) seconds. Express the answer using three significant figures.
\[ P = \]
Submission requires expressing the power in horsepower (hp).
**Additional Features**
- The image provides a digital input box for users to submit their calculations.
- Options for providing feedback on the problem are available.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc846a080-c87d-4490-a2a5-bc99fd5c8d6b%2F2145cd9a-fc9f-40a0-95f3-c0e101a6d154%2Feyf12jj_processed.jpeg&w=3840&q=75)
