Answer:
160790 J
Explanation:
We can find the heat necessary for the ice to go from -20 degrees Celsius to 0 degrees Celsius:
Where 
is the specific heat of ice, that is the amount of heat that must be supplied per unit mass to raise its temperature in a unit.
We must calculate the latent heat of fusion required for this ice mass to change to water:
Where H=334 J/g is the specific latent heat of fusion of water, that is the amount of energy needed per unit mass of a substance at its melting point to change from the solid to the liquid state.
Then we calculate the heat necessary for the water to go from 0 degrees Celsius to 20 degrees Celsius:
Where 
is the specific heat of water, that is the amount of heat that must be supplied per unit mass to raise its temperature in a unit.
Finally the 3 results are added:

Answer:
Let's say the pitcher is angry or just has a really heavy hand while throwing this ball, and now you have to catch it, otherwise it's going to ram into your face. When you put your hands up just in time to catch this ball, this is called impulse, or commonly expressed as a reflex. Depending on what kind of ball is being thrown, such as a golf ball, baseball, basketball, beach-ball, rubber-ball, baseball, etc. ... the weight of the ball itself is going to impact how much it i going to hurt when you catch it without any hand protection. However, if you're catching, let's say a baseball, with a padded glove, it is not going to hurt as bad as catching the baseball bare handed, because the padded glove has enough padding in it to create a barrier between the skin of your hand and the palm of the glove.
