force-weight=mass*a
825-55g=55a
solve for acceleration a.
A 55-kg female bungee
jumper fastens one end of
the cord (made of elastic
material) to her ankle and the
other end to a bridge. Then
she jumps off the bridge. As
the cord is stretching, it exerts
an elastic force directed up on
her. Calculate her acceleration
at the instant the cord exerts
an elastic force of 825 N [up]
on her.
