You push your little sister on a swing and in

1.5 minutes you make 51 pushes.

What is the frequency of your swing? An-

swer in units of Hz.

1.5 minutes=90 seconds

frequency=cycles per second

51/90= fequency in hertz

convert 1.5 to seconds,

then divide 51 by that.

51/1.5=34push/min=0.566666push/sec.
