Determine the kinetic energy of a 1000-kg roller coaster car that is moving with a speed of 20.0 m/s.
Question
Determine the kinetic energy of a 1000-kg roller coaster car that is moving with a speed of 20.0 m/s.
Solution
The kinetic energy (KE) of an object can be calculated using the formula:
KE = 1/2 * m * v^2
where: m is the mass of the object, and v is the speed of the object.
In this case, the mass (m) of the roller coaster car is 1000 kg and the speed (v) is 20.0 m/s.
Substituting these values into the formula gives:
KE = 1/2 * 1000 kg * (20.0 m/s)^2
Solving the equation:
KE = 1/2 * 1000 kg * 400 m^2/s^2 KE = 200,000 Joules
So, the kinetic energy of the roller coaster car is 200,000 Joules.
