The mechanical energy lost by the car is 246415.84 J.
What is mechanical energy?
This can be defined as the energy possessed by a body due to motion or due to its position.
To calculate the mechanical energy lost, we use the formula below.
Formula:
- E' = μkmv².................. Equation 1
Where:
- E' = Mechanical energy lost of the car
- μk = coefficient of kinetic energy
- m = mass of the car
- v = velocity of the car.
From the question,
Given:
- m = 987 kg
- v = 28.8 m/s
- μk = 0.301
Substitute these values into equation 1
- E' = 987(28.8)²(0.301)
- E' = 246415.84 J.
Hence, The mechanical energy lost by the car is 246415.84 J.
