B. A mass of 0.25kg is dropped from rest in a medium offering a resistance of 0.2 times the velocity, where v is measured in meters/sec. (You should use a calculator or Wolfram Alpha to calculate numbers.) your a) If the mass is dropped from a height of 30m, determine its velocity when it hits the ground. (Answ: 11.58 m/s) b) The object is designed to withstand an impact at no more than 10m/s. What is the maximum height that it can be dropped from? (Answ: 13.45m)
