Calculating Kinetic Energy of a Bike and Rider

What is the kinetic energy of a bike and rider moving at a speed of 6 m/s with a combined mass of 60 kg?

Answer:

The kinetic energy of the bike and rider moving at a speed of 6 m/s with a combined mass of 60 kg is 1080 Joules.

Explanation:

Kinetic energy is the energy of an object due to its motion. It is calculated using the formula: KE = 1/2 * m * v^2, where 'm' is the mass of the object, and 'v' is its velocity.

In this scenario, the bike and rider have a combined mass of 60 kg and are moving at a speed of 6 m/s. Substituting these values into the formula:

  • KE = 1/2 * 60 kg * (6 m/s)^2
  • KE = 1/2 * 60 kg * 36 m^2/s^2
  • KE = 1080 Joules

Therefore, the kinetic energy of the bike and rider is 1080 Joules. Kinetic energy is directly proportional to the mass and the square of the velocity, meaning that an increase in mass or velocity will result in a higher kinetic energy.
