A1500kg space probe is moving at constant velocity of 4200m/sec. in a course change maneuver the rocket engines fire for 5 minutes increasing the probe's velocity to 5000m/sec. what is the probe's change in kinetic energy? a. 3.68x10^6 j. b. 5.52x10^9 j c. 1.1x10^10 j d. not enough info.

Aproduction line at v. j. sugumaran's machine shop has three stations. the first station can process a unit in 7 minutes. the second station has two identical machines, each of which can process a unit in 16 minutes (each unit only needs to be processed on one of the two machines). the third station can process a unit in 10 minutes. ▼ is the bottleneck station, with a bottleneck time of nothing minutes per unit (enter your response as a whole number).
