A space ship at rest on a launch pad has a mass of 1.00 × 10⁵ kg. How much will its energy have increased when the ship is moving at 0.600c?

Question

Quizplus · Accepted Answer

The equation for kinetic energy of a moving object is KE = (1/2)mv^2, where m is the mass of the object and v is its velocity. Since the spaceship is moving at 0.600c, we can calculate its velocity as v = 0.600c = 1.80 × 10S1U1P8S1S1P m/s. Plugging in the values, we get KE = (1/2)(1.00 × 10⁵ kg) (1.80 × 10S1U1P8S1S1P m/s)^2 = 2.25 × 10²¹ J. Therefore, the spaceship's energy has increased by 2.25 × 10²¹ J.
