1. A rock is dropped from a bridge which is 150 feet above a river. The height, in feet, of the rock above the surface of the water after & seconds is given by the s() = 150 -16t?. a. How far does the ball travel in the time interval from 2 seconds to 2.5 seconds? b. Find the average velocity over [2,2.5]. c. Find the average velocity over the intervals [2,2.1], [2,2.01], [2,2.001] and [2,2.0001] and use the results to estimate the instantaneous velocity at t = 2 seconds. Interval Average Velocity [2,2.1] [2,2.01] [2,2.001] [2,2.0001] Instantaneous Velocity at ( = 2 seconds
