Answer:
4. 1. 2. 3.
Step-by-step explanation:
The potential energy here is gravitational potential energy which is the equation mgh. m = mass, g = gravity (9.8) h = height. With this we can solve each of the given cases. 1. would turn out to be 784, 2. 1176, 3. 9800 and 4. 245. We can then compare which one is smallest and that would go first. In this case 4. So the order from least to greatest is 4. 1. 2. 3.
