JudyThe energy expended depends on various factors like the mass of the Baseball, its velocity, air resistance, and other forces acting on it. However, if we assume ideal conditions, you can calculate the energy using the formula for kinetic energy: KE = 0.5 * mass * velocity^2. Once you have the kinetic energy value in joules, you can compare it to the energy expended by the baseball as it travels 30 meters.

How many watts in 7000 joules?
To convert joules to watts, you need to know the time over which the energy is expended. Since power in watts is defined as energy in joules divided by time in seconds, you cannot directly convert 7000 joules to watts without knowing the time duration.
What does the term energy expended over time mean in physics?
In physics, energy expended over time refers to the rate at which energy is used or transferred. This is typically measured in units like watts (Joules per second) to quantify how quickly energy is being consumed, produced, or transformed in a system.
What is 6 million joules in watts?
To convert joules to watts, you need to know the time period over which the energy is expended. Watts = Joules / seconds. Without this information, it is not possible to directly convert 6 million joules to watts.
What is the difference between joules and watts?
Joules (J) measure energy, while watts (W) measure power. Power is the rate at which energy is expended or transferred, so 1 watt is equal to 1 joule per second. In other words, watts represent the amount of energy consumed or produced per unit of time.
What quantity has units of joules?
Energy has units of joules.
