A hiker inspects a tree frog sitting on a small stick in his hand.Suddenly startled, the hiker drops the stick from rest at aheight of 1.85 m above the ground and, at the same instant,the frog leaps vertically upward, pushing the stick down sothat it hits the ground 0.450 s later. Find the height of the frogat the instant the stick hits the ground if the frog and the stickhave masses of 7.25 g and 4.50 g, respectively. (Hint: Find thecenter-of-mass height at t = 0.450 s for the frog–stick systemand then use the definition of center of mass to solve for thefrog’s height.)

Question
A hiker inspects a tree frog sitting on a small stick in his hand.
Suddenly startled, the hiker drops the stick from rest at a
height of 1.85 m above the ground and, at the same instant,
the frog leaps vertically upward, pushing the stick down so
that it hits the ground 0.450 s later. Find the height of the frog
at the instant the stick hits the ground if the frog and the stick
have masses of 7.25 g and 4.50 g, respectively. (Hint: Find the
center-of-mass height at t = 0.450 s for the frog–stick system
and then use the definition of center of mass to solve for the
frog’s height.)
