An object is thrown directly downward from the top of a cliff. The distance that the object has fallen in meters after t seconds is given by the function d(t) = 5t + 4.9t2, t ≥ 0. a) Determine the average rate of change of the distance fallen for each interval. i) 0 ≤ t ≤ 3ii) 2 ≤ t ≤ 4iii) 3 ≤ t ≤ 5 b) Sketch a graph of the function on a separate sheet of paper.  c) Use a difference quotient to estimate the instantaneous rate of change of the distance fallen at each time. i) t = 2 sii) t = 4 s

Equation of Waves

Wave is an oscillation or disturbance traveling in a medium. It performs the transportation of energy but does not carry any matter. This motion of waves will transport fuel in a medium without permanent transfer of mass (particle).
