A batter checks her swing as a $0.15-\mathrm{kg}$ baseball crosses home plate outside the strike zone. If the separation between the batter and the ball is $0.77 \mathrm{~m}$ and the gravitational force exerted on the batter by the ball is $1.1 \times 10^{-9} \mathrm{~N}$, what is the mass of the batter?

Step 1

Step 1: We start by writing down the Newton's law of universal gravitation: \[F = G \frac{m_1 m_2}{r^2}\] where $F$ is the gravitational force, $G$ is the gravitational constant, $m_1$ and $m_2$ are the masses of the two objects, and $r$ is the distance Show more…

Key Concepts

Newton's Law of Universal Gravitation

This law states that every two objects in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. It is expressed with the formula F = G * (m1 * m2) / r², which allows us to calculate an unknown mass or the force if the other quantities are known.

Gravitational Constant (G)

The gravitational constant is a fundamental physical constant that appears in Newton's law of universal gravitation. It quantifies the strength of the gravitational force in the equation and is necessary to relate the masses and distance to the resulting gravitational force. Its known value is key to solving problems involving gravitational interactions in classical mechanics.
