Answer to Question #150904 in General Chemistry for Lyna Moinifar

Question

What is the kinetic energy in kilojoules of a space station weighing 8042 kg and moving at a velocity of 2.603e+4 km/hr?

Answer 1

Kinetic energy=?

Mass= 8042Kg

Velocity= 2.603e+4Km/h = 2603m/s (by conversion)

Kinetic energy = 1/2mv²

Kinetic energy = 1/2 x 8042x 2063²

Kinetic energy = 1.71x10¹⁰J

Kinetic energy = 1.71x10⁷Kj
