How do i find this? A shooting star is a meteor that burns up when it reaches Earth's atmosphere. Many of these meteoroids are quite small. Calculate the kinetic energy of a meteoroid of mass 6.0 g moving at a speed of 45 km/s and compare it to the kinetic energy of a 1400-kg car moving at 29 m/s (65 mi/h). (Find kinetic energy of the meteor and of the car)

KE= 1/2 m v^2 where m is in kg, and v in m/s.

Compute that for both, and compare.

i got 6.075E12 for the meteor

and 588,700 for the car, but both answers are still wrong.

To find the kinetic energy of an object, you can use the formula:

Kinetic Energy (KE) = 0.5 * mass * velocity^2

First, let's calculate the kinetic energy of the meteoroid:

Mass of the meteoroid = 6.0 g = 0.006 kg
Velocity of the meteoroid = 45 km/s

Kinetic Energy of the meteoroid = 0.5 * 0.006 kg * (45,000 m/s)^2

To convert km/s to m/s, we need to multiply by 1000:
Velocity of the meteoroid in m/s = 45,000 m/s

Therefore, Kinetic Energy of the meteoroid ≈ 0.5 * 0.006 kg * (45,000 m/s)^2

Now, let's calculate the kinetic energy of the car:

Mass of the car = 1400 kg
Velocity of the car = 29 m/s

Kinetic Energy of the car = 0.5 * 1400 kg * (29 m/s)^2

Comparing the two values will give us an idea of the difference in kinetic energy between the meteoroid and the car.
