If you launch a ball into the air with an initial velocity of 65 feet per second from an initial height of 10 ft, the height of the ball (in ft) t seconds after you throw the ball (ignoring air resistance) is given by function: h(t) = 10 + 65t - 16t2 Compute the average velocity for the time period beginning when t = 1 and lasting... 0.1 seconds: ft/sec 0.01 seconds: ft/sec 0.001 seconds: ft/sec 0.0001 seconds: ft/sec Now use these average velocities to estimate the instanteneous velocity when t = 1: ft/sec
