What is the velocity of the other rock

Reference no: EM1322094

Q1. Two rocks collide in outer space. Before the collision, one rock had mass 13 kg and velocity ‹ 4400, -2950, 2300 › m/s. The other rock had mass 8.0 kg and velocity ‹ -700, 1950, 3750 › m/s. A 1.0 kg chunk of the first rock breaks off and sticks to the second rock. After the collision the 12.0 kg rock has velocity ‹ 1400, 250, 2050 › m/s. After the collision, what is the velocity of the other rock, which's mass, is now 9.0 kg?

Q2. According to the law of universal gravitation, what will happen to Earth if the Sun were somehow replaced by the black hole of same mass?
