newtons second law of motion states that:
every action has an equal and opposite reaction
an object at rest will tend to stay at rest
an object in motion will tend to stay in motion
the acceleration a body experiences is directly proportional to the force causing it and takes place in the same direction as the force

Explanation:

1. The measure of how much matter an object has is its mass. This is a fundamental concept in physics.
2. For the baseball - throwing question, the range formula for a projectile (neglecting air - resistance) is \(R=\frac{v_{0}^{2}\sin2\theta}{g}\), where \(v_{0}\) is the initial velocity, \(\theta\) is the angle of projection, and \(g\) is the acceleration due to gravity. The range \(R\) is maximized when \(\sin2\theta = 1\), which occurs when \(2\theta=90^{\circ}\) or \(\theta = 45^{\circ}\).
3. Newton's second law of motion states that the acceleration a body experiences is directly proportional to the force causing it and takes place in the same direction as the force (\(F = ma\)). The statement "every action has an equal and opposite reaction" is Newton's third law, and "an object at rest will tend to stay at rest" and "an object in motion will tend to stay in motion" are parts of Newton's first law.

Answer:

1. mass
2. C. 45 degrees
3. D. the acceleration a body experiences is directly proportional to the force causing it and takes place in the same direction as the force
