1. A dime is accidentally dropped from the top of the Tokyo Tower. The height, h, in meters of the dime above the ground at t seconds can be modelled by h(t) = 4.9t* + 333 a) Determine the average rate of change between the third and fourth second of the dime's fall [3 marks A] b) Estimate the instantaneous rate of change at t = 8.2 seconds (Just before impact).
