how to pivot corners in jrotc?
i forgot how to pivot corners when you turn left you pivot on the ball of your right foot and when you turn right you pivot on the ball of your left foot is this right
Yes you are correct.
Be sure to not round the corner when you set your pivot foot. This means don't start turning until you have set your foot.
By doing this you will look like you walked straight into the pivot point and not all nasty and crooked.

What is centripetal acceleration & what is the magnitude of force.?
A fast pitch softball player does a "windmill" pitch, moving her hand through a vertical circular arc to pitch a ball at 72mph. The 0.18kg ball is 50cm from the pivot point at her shoulder.
a)Just before the ball leaves her hand, what is its centripetal acceleration?
b)At the lowest point of the circle the ball has reached its maximum speed. What is the magnitude of the force her hand exerts on the ball at this point?
We are given v=72mi/hr and we have to convert that to meters/second:
72mi/hr*1.609km/mi*1hr/3600s*1000m/km
=32.18m/s
CA=v^2/r=(32.18^2)/.5=2071.1m/s^2 a)
For b assume the speed at the lowest point of the circle is 72mph=32.18ms/s and the centripedal force is m(v^2)/r
=372.8N and add weight +9.81*.18kg
= 374.6N b)
