A 32 kg object at rest on the origin of an xy plane explodes into 3 pieces. A 10 plece moves at 8 m/s at an angle of to the x-axis, a 15 kg piece moves at 4 m/s at an angle of 114 degrees to the x axis. What is the magnitude of the final velocity of the third plece?

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
