Answer :
The kinetic energy of this car is equal to 77160.49 Joules.
How to calculate the kinetic energy of this car?
In Mathematics, the kinetic energy of a physical object can be calculated by using the following equation (formula):
K.E = 1/2 × mv²
Where:
- K.E represent the kinetic energy.
- m represent the mass.
- v represent the speed or velocity.
Note: 50 km/h to m/s = 50 × 1000/3600 = 13.89 m/s
By substituting the given parameters into the formula for the kinetic energy of a physical object, we have the following:
Kinetic energy, K.E = 1/2 × 800 × 13.89²
Kinetic energy, K.E = 400 × 192.90
Kinetic energy, K.E = 77160.49 Joules.
