Question 30





A small piece of Styrofoam packing material is dropped from a height of h = m above the ground. Until it reaches terminal speed, the magnitude of its acceleration is given by a = g - Bv. After falling h1 = m, the Styrofoam effectively reaches terminal speed and then takes t = s more to reach the ground.
(a) What is the value of the constant B?
(b) What is the acceleration at t = 0?
(c) What is the acceleration when the speed is v = m/s?
