The deck of a bridge is suspended 215 feet above a river. If a pebble falls off the side of the bridge, the height, in feet, of the pebble above the water surface after t seconds is given by y = 215 – 16t2. (a) Find the average velocity (in ft/s) of the pebble for the time period beginning when t = 3 and lasting the following amount of time. (i) 0.1 seconds 214.84 X ft/s (ii) 0.05 seconds 214.96 x ft/s (iii) 0.01 seconds 214.998 X ft/s (b) Estimate the instantaneous velocity (in ft/s) of the pebble after 3 seconds. 71 × ft/s
