If you launch a ball into the air with an initial velocity of 61 feet per second from an initial height of 16 ft, the height of the ball (in ft) t seconds after you throw the ball (ignoring air resistance) is given by function: h(t) = 16 + 61t - 16t2 Compute the average velocity for the time period beginning when t = 2 and lasting... 0.01 seconds: 52.9566 x ft/sec 0.005 seconds: ft/ sec 0.002 seconds: ft/ sec 0.001 seconds: ft/ sec Now use these average velocities to estimate the instanteneous velocity when t = 2: ft/sec
