To calculate the kinetic energy of each vehicle, we can use the equation:
Kinetic energy = 1/2 * mass * velocity^2
For the truck:
Mass = 6000 kg
Velocity = 92 km/h = 25.56 m/s (we convert to meters per second since the standard units for mass and velocity in the kinetic energy equation are kilograms and meters per second, respectively)
Kinetic energy = 1/2 * 6000 kg * (25.56 m/s)^2
Kinetic energy = 4,668,876 Joules
Therefore, the kinetic energy of the truck is approximately 4.67 million Joules.
For the car:
Mass = 1200 kg
Velocity = 100 km/h = 27.78 m/s
Kinetic energy = 1/2 * 1200 kg * (27.78 m/s)^2
Kinetic energy = 1,875,840 Joules
Therefore, the kinetic energy of the car is approximately 1.88 million Joules.
Using the image below, figure out the kinetic energy of each vehicle.
Truck: 6000 kg 92km/h
Car:1200 kg 100km/h
