**Physics Problem: Work and Energy**Consider the following situation: You are throwing a ball to a friend while taking a physics class, and you begin to wonder about the concept of work.**Problem Statement:**You know that when you throw, you exert a force of 655 N on the ball (which has a mass of 1.84 kg), and that you do so for a distance of 0.27 m. If you start the throw from rest, what is the final speed of the ball?**Instructions:**When you show your work for this question, you must do the calculations using principles of work and energy for credit. If you use kinematics, you will not receive credit.**Provide Your Answer Below:**- Answer: [_________]- Units: [_________]To explain the calculation in detail:1. **Calculate the Work Done:** - Work $ W $ is given by the formula $ W = F \cdot d $ where $ F $ is the force and $ d $ is the distance. - Here, $ F = 655 \, \text{N} $ and $ d = 0.27 \, \text{m} $.2. **Determine the Kinetic Energy:** - The work done on the ball is converted into its kinetic energy $ \left( \frac{1}{2}mv^2 \right) $. - Thus, $ W = \frac{1}{2}mv^2 $, where $ m $ is the mass of the ball and $ v $ is its final velocity.3. **Solve for Final Velocity:** - Equate the work done to the kinetic energy and solve for $ v $.Remember to express your final answer with the appropriate units.
