What is the kinetic energy in joules of a 950-lb motorcycle moving

In summary, kinetic energy is the energy that an object possesses due to its motion, calculated using the formula KE = 1/2 * m * v^2, and measured in joules (J). The mass of a 950-lb motorcycle is approximately 431 kilograms (kg), and the kinetic energy of a 950-lb motorcycle moving at 60 miles per hour is approximately 1,521,609 joules.

You already posted this in the homework section, this area isn't for homework problems, and this problem has nothing to do with chemistry.

You hit the trifecta.
 

1. What is kinetic energy?

Kinetic energy is the energy that an object possesses due to its motion.

2. How is kinetic energy calculated?

Kinetic energy is calculated using the formula KE = 1/2 * m * v^2, where m is the mass of the object and v is its velocity.

3. What is the unit of measurement for kinetic energy?

Kinetic energy is measured in joules (J).

4. What is the mass of a 950-lb motorcycle?

The mass of a 950-lb motorcycle is approximately 431 kilograms (kg).

5. What is the kinetic energy in joules of a 950-lb motorcycle moving at 60 miles per hour?

Using the formula KE = 1/2 * m * v^2, the kinetic energy of a 950-lb motorcycle moving at 60 miles per hour (26.8 meters per second) would be approximately 1,521,609 joules.
