The Energetic Textbook Journey

How much kinetic energy does a 0.45 kg textbook have when sliding at a speed of 0.20 m/s?

The kinetic energy of the textbook can be calculated using the formula: Kinetic Energy = 1/2 * mass * velocity^2. Given that the mass of the textbook is 0.45 kg and its speed is 0.20 m/s, we can plug these values into the formula to find the kinetic energy.

Kinetic energy is the energy an object possesses due to its motion. In this case, the textbook has a mass of 0.45 kg and is moving at a speed of 0.20 m/s. By substituting these values into the formula for kinetic energy, we can calculate the kinetic energy of the textbook.

The formula for kinetic energy is: KE = 1/2 * m * v^2, where m is the mass of the object and v is its velocity. Plugging in the given values:

KE = 1/2 * 0.45 * (0.20)^2

KE = 1/2 * 0.45 * 0.04

KE = 0.0225 J

Therefore, the kinetic energy of the 0.45 kg textbook sliding at a speed of 0.20 m/s is 0.0225 joules.
