Can someone check my work ### Problem 14If a man runs at a constant speed of 4 m/s for 40 seconds and then he runs back at 8 m/s to his starting position:**Diagram Explanation:**- Distance (d) with a speed of 4 m/s over time \( t_1 = 40 \, \text{sec} \)- Returns at 8 m/s over time \( t_2 = \text{calculated} \)**Calculations:**1. **Distance Calculation:** - Speed × Time = Distance - \( d = 4 \times 40 = 160 \, \text{m} \)2. **Going Back:** - \( 160 \, \text{m} = 8 \times t_2 \) - \( t_2 = 20 \, \text{seconds} \)3. **Total Time:** - \( 40 + 20 = 60 \, \text{seconds} \)4. **Total Distance:** - \( \text{Total distance} = d + d = 2(160) = 320 \, \text{m} \)5. **Average Speed:** - \(\text{Average speed} = \frac{\text{distance}}{\text{time}} = \frac{320}{60 \, \text{sec}} = \frac{16}{3} \, \text{m/s}\)6. **Displacement:** - Defined as the minimum distance between initial and final positions. - \( s = 0 \, \text{m} \)7. **Average Velocity:** - \(\text{Average velocity} = \frac{\text{displacement}}{\text{time}} = \frac{0 \, \text{m}}{60 \, \text{sec}} = 0 \, \text{m/s}\)**Note:** The direction cannot be defined as the displacement is zero. **Problem Statement:**14. If a man ran at a constant 4 m/s for 40 s and then he ran at 8 m/s back to his starting position.*Insert below a screenshot of your worksheet which shows how you obtain the final answer for each question.*a. What was the total time of his run? _______ sb. What would be the total distance he covered? _______ mc. What would be his average speed? _______ m/sd. What was his displacement at the end of his trip? _______ me. What was his average velocity? _______ m/s and direction (if any) _______
