Question

Use the data provided to calculate the amount of heat generated for each cylinder height. Round your answers to the nearest tenth.

100m: kJ
200 m: kJ
1000 m: kJ

Answer 1

100m: 4.9 kJ

200m: 9.8 kJ

1000m: 49.1 kJ

Answer 2

Answer:

100m: 4.9 kJ

200m: 9.8 kJ

1000m: 49.1 kJ

Explanation:

In order to calculate this, you just have to calculate the PE of every cilynder, and as you know the PE is calculated with the next formula:

$PE=G*H*M\\PE=Potential-Energy\\G=Gravity\\H=Height\\M=Mass$

SO we just hve to insert the values into the formula to get our results, remember that the height will change with every sample because we are putting the cylinder at different heights:

100m:

$PE=G*H*M\\PE=9.8*100*5kg= 4900 joules=4.9Kj$

200m:

$PE=G*H*M\\PE=9.8*200*1kg= 9800 joules=9.8Kj$

1000m:

$PE=G*H*M\\PE=9.8*1000*1kg= 49100 joules=49.1Kj$

And you have the different heat generated by each cilynder at different heights.
