An "extreme" pogo stick utilizes a spring whose uncompressed length is 48 and whose force constant is 1.1×104 . A 53-kg enthusiast is jumping on the pogo stick, compressing the spring to a length of only 5.0 at the bottom of her jump.

A) Calculate the net upward force on her at the moment the spring reaches its greatest compression.

B) Calculate her upward acceleration, in g's at that moment.
