How to Calculate Kinetic Energy of a Bike and Rider?
What is the kinetic energy of the bike and rider?
A bike (mass of bike + rider = 85 kg) is coasting on a flat road at 10 m/s. How can we calculate the kinetic energy of the bike and rider in this scenario?
Calculating Kinetic Energy of the Bike and Rider
To calculate the kinetic energy of an object, including a bike and rider in this case, we use the formula: Kinetic Energy (K) = 1/2 mass (m) x velocity (v)^2. In this scenario, the mass of the bike and rider is given as 85 kg and the velocity is 10 m/s.
To calculate the kinetic energy, we need to plug in the values into the formula. Substituting the values, we get:
Kinetic Energy (K) = 1/2 x 85 kg x (10 m/s)^2
Calculating further:
Kinetic Energy (K) = 1/2 x 85 x 100
Kinetic Energy (K) = 42.5 x 100
Kinetic Energy (K) = 4250 joules
Therefore, the kinetic energy of the bike and rider coasting on a flat road at 10 m/s is 4250 joules.
