A 70-kg runner begins his slide into second base where he is moving at a speed of 40.0 m/s. The coefficient of kinetic friction between his clothes and Earth is 0.70. He slides so that his speed is zero just as he reaches the base.

Why does pressure increase in space?

What are the seven different forms of energy? Give an example of each.

Determine the total mechanical energy of a 250 g baseball if it has a velocity of 30 m/s when it leaves the pitcher's hand 1.2m above the ground.

When distances were carefully measured from Earth to globular clusters above and below the Milky Way plane (where our view of them is not obscured by interstellar dust and gas), their distribution was found to be

Imagine you transfer heat into a gas. This heat splits up in two different ways: Additional thermal energy making the gas hotter and "fuel" for the gas to do work. Let's suppose, 64% of the transferred heat transforms into thermal energy.

How much heat is absorbed by a 61g iron skillet when its temperature rises from 5oC to 29oC?

Explain the relationship between motion and frame of reference.
