Answer to Question #168996 in Physics for Monica

Question

Gregory launches a flying plane with a mass of 52.5 g (or 0.0525 kg) with a velocity of 20.0 m/s east. Sam launches a fyling cat (m=0.0695 kg) with a velocity of 18.0 m/s south. The brothers lauches a flying disc (m=0.0485 kg) with a velocity of 25.0 m/s at 37 degrees NW. The sisters attempt to lauch a monkey but merely rip the arm off of it. Clyde sits back and watches the disaster. What is the final velocity of the three ( plane, disc and monkey)?

Answer 1

The final velocity of the three bodies (neglecting air resistance) will be 20 m/s for the plane, 25 m/s for the disc, and 0 m/s for the monkey because it was not launched.
