### Physics Problem: Calculating Net Force Using Newton's Second Law**Problem Statement:**A runner with a mass of 70 kg accelerates from 0 m/s to 8 m/s in 9 s. Find the magnitude of the net force (in newtons) on the runner using the alternate form of Newton's second law. Round your answer to the nearest whole number. **Solution Guide:**1. **Identify Given Information:** - Mass (\( m \)) = 70 kg - Initial velocity (\( u \)) = 0 m/s - Final velocity (\( v \)) = 8 m/s - Time (\( t \)) = 9 s2. **Determine Acceleration:** - Acceleration (\( a \)) can be calculated using the formula: \[ a = \frac{v - u}{t} \] - Substitute the given values: \[ a = \frac{8 \, \text{m/s} - 0 \, \text{m/s}}{9 \, \text{s}} = \frac{8}{9} \, \text{m/s}^2 \]3. **Apply Newton's Second Law of Motion:** - Newton's second law states that the net force (\( F \)) is the product of mass and acceleration: \[ F = m \times a \] - Substitute the given values and calculated acceleration: \[ F = 70 \, \text{kg} \times \frac{8}{9} \, \text{m/s}^2 = \frac{560}{9} \, \text{N} \approx 62.22 \, \text{N} \]4. **Round the Answer:** - The magnitude of the net force, rounded to the nearest whole number, is: \[ F \approx 62 \, \text{N} \]**Answer:**The net force on the runner is approximately **62 newtons**.
