Two objects with masses M₁ = 30,000 kg and M₂ = 70,000 kg are initially very far apart and at rest. If due to gravitational attraction the two objects attract each other, calculate their total kinetic energy when their centers of masses are 100 km apart. A) 1.4 * 10^-3 J B) 1.4 * 10^-11 J C) 1.4 *10^-6J D) 0.7 * 10^-3 J E) 0.7 * 10^-6 J

Question

Quizplus · Accepted Answer

The total kinetic energy gained by the system is equal to the gravitational potential energy lost, which is calculated using the formula: $ U = \frac{G \cdot M_1 \cdot M_2}{r} $. Substituting the given values, the total kinetic energy is approximately 1.4 * 10^-6 J.

Two Objects with Masses M1 = 30,000 Kg and M2

Two Objects with Masses M₁ = 30,000 Kg and M₂
