Question

Consider a grey squirrel falling out of a tree to the ground. (a) If we ignore air resistance in this case (only for the sake of this problem), determine a squirrel's velocity just before hitting the ground, assuming it fell from a height of 3.0 m. (b) If the squirrel stops in a distance of 2.0 cm through bending its limbs, compare its deceleration with that of the airman in the previous problem.

a) $-7.7 \textrm{ m/s}$

b) $1.5 \times 10^3 \textrm{ m/s}^2$, which is 3 times the acceleration of pilots landing without parachutes.
