Answer 2

Calculating Kinetic Energy of a Spacecraft

To calculate the kinetic energy of the spacecraft, we can use the formula for kinetic energy:

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

Where: - mass = 24 tonnes (which is equivalent to 24,000 kg) - velocity = 0.8c (where c is the speed of light)

Calculation

Substituting the given values into the formula:

KE = 0.5 * 24000 kg * (0.8c)^2

To calculate the kinetic energy, we need to convert the velocity from a fraction of the speed of light to meters per second. The speed of light, c, is approximately 299,792,458 meters per second.

Converting 0.8c to meters per second: 0.8c = 0.8 * 299,792,458 m/s = 239,833,966.4 m/s

Now, we can calculate the kinetic energy using the converted velocity:

KE = 0.5 * 24000 kg * (239,833,966.4 m/s)^2

Result

After performing the calculation, the kinetic energy of the spacecraft is approximately 2.73 x 10^24 joules.
