After picking up several staples with the device, what change would enable Tony to drop the staples in the scrap metal bin? Removing the battery removing the iron nail moving the wire loops closer together spreading the wire loops farther apart

To find the change in centripetal acceleration, you should first look for the centripetal acceleration at the top of the hill and at the bottom of the hill.

The formula for centripetal acceleration is:
Centripetal Acceleration = v squared divided by r

where:
v = velocity, m/s

assuming the velocity does not change:

at the top of the hill:
centripetal acceleration = (4.5 m/s^2) divided by 0.25 m
= 81 m/s^2

at the bottom of the hill:
centripetal acceleration = (4.5 m/s^2) divided by 1.25 m
= 16.2 m/s^2

to find the change in centripetal acceleration, take the difference of the two.
change in centripetal acceleration = centripetal acceleration at the top of the hill – centripetal acceleration at the bottom of the hill

= 81 m/s^2 – 16.2 m/s^2
= 64.8 m/s^2 or 65 m/s^2
