8/20 There is a bell at the top of đ tower that is 45 m high . The bell weighs 100 kg . What is the potential energy of the bell? 4,500 J 980J 441 J 44.10 o J

## Step 1<br />The potential energy (PE) of an object can be calculated using the formula:<br />### **PE = mgh**<br />where:<br />- \(m\) is the mass of the object (in kilograms),<br />- \(g\) is the acceleration due to gravity (approximately 9.8 m/s² on Earth),<br />- \(h\) is the height above the ground (in meters).<br /><br />## Step 2<br />In this problem, the mass of the bell (\(m\)) is 100 kg, the acceleration due to gravity (\(g\)) is 9.8 m/s², and the height (\(h\)) is 45 m.<br /><br />## Step 3<br />Substitute these values into the formula to calculate the potential energy:<br />### **PE = 100 kg * 9.8 m/s² * 45 m**
