At what point in its motion is the KE of ta pendulum bob a maximum? At what point is its PE at maximum? When its KE is half its maximum value, how much PE does it have?

he kicked it 10 feet straight up into the air? i think this works.

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.

f=ma newton

f=100x2.5=250n

i had this question and the answer was 3.15 miles.
