Each person on the lift weighs 70 kg.What is the total force the lift must hold to keep themstill7 HHintForce=Masstimes Gravity,withg=9.8m/s^2) 2. Lift Stops

1. **Understanding the Problem:** The question asks for the total force the lift must exert to counteract the weight of the people inside. Weight is a force caused by gravity pulling down on mass.<br /><br />2. **Identifying the Knowns:**<br /> * Mass per person (m): 70 kg<br /> * Number of people: 7<br /> * Acceleration due to gravity (g): 9.8 m/s²<br /><br />3. **Calculating the Total Mass:**<br /> * Total mass (M) = mass per person * number of people<br /> * M = 70 kg/person * 7 people<br /> * M = 490 kg<br /><br />4. **Calculating the Total Force (Weight):**<br /> * Force (F) = Mass (M) * Acceleration due to gravity (g)<br /> * F = 490 kg * 9.8 m/s²<br /> * F = 4802 N (Newtons)<br /><br />5. **Answer:** The lift must hold a force of 4802 Newtons to keep the people still.<br />
