A 520g bowl sitting on a table undergoes an explosive force sending pieces off in every direction. You were able to collect the following information:

  1. A 100 gram piece had a velocity of 10 m/s at 45 degrees
  2. A 250 gram piece had a velocity of 6 m/s at 135 degrees
  3. You know there has to be another piece. How heavy must the piece be and how fast was its velocity?

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...
