Packages are dropped at regular intervals from a low-flying plane to the level ground below. The plane is flying at a height of 200 m with a constant speed of 40 m/s and the packages are being dropped at a rate of one package every two seconds. Air resistance may be ignored. As the packages are falling through the air their distance of separation will
  • A. decrease.
  • B. increase.
  • C. remain constant.
  • D. depend on the mass of the packages.

A jet accelerates at a=3.92 m/s^2 from rest until it reaches its takeoff velocity of 360 km/hr. It has to travel for 5 seconds at its takeoff velocity before taking off. What's the minimum distance that the jet will travel on the runway? A car backs up at a constant speed for a short time, then applies the brakes and steadily comes to rest. Sketch velocity-time and position-time graphs that depict the car's motion. Assume that the forward direction is...
