Question

When a click beetle is upside down on its back, it jumps
upward by suddenly arching its back, transferring energy stored in a
muscle to mechanical energy.This launching mechanism produces an
audible click, giving the beetle its name.Videotape of a certain clickbeetle
jump shows that a beetle of mass m = 4.0 * 10-6 kg moved directly
upward by 0.77 mm during the launch and then to a maximum
height of h= 0.30 m. During the launch, what are the average magnitudes
of (a) the external force on the beetle’s back from the floor
and (b) the acceleration of the beetle in terms of g?
