A person drops a ball of 100g at rest from a height of 1000m. He observes that there is air resistance (in newtons) acting on the body and it is proportional to the velocity v (in meters per second). He also notes that the limiting velocity is 245 meters per second. a) What is the velocity and distance after t seconds? b) What is the time t at which the velocity will be one-fifth of the limiting velocity?
