A squirrel falls from a very tall tree. Initially at t= 0), the squirrel is at the top of the tree, a distance y 50 m above the ground. At t = 1.0 s, the squirrel is at y 45 m, and at t = 2.0 s, it is at y 30 m. Estimate the average velocity of the squirrel during the intervals from t= 0.0 s to t =1.0 s and from t= 1.0 s to t =2.0 s. Use these results to estimate the average acceleration of the squirrel during this time.
