PHYSICS:CHAPTER 6 REVIEW WORKSHEET
NAME ___________________________

SHOW ALL WORK AND UNITS FOR THE FOLLOWING PROBLEMS.

  1. A stone is thrown horizontally at a speed of 25 m/s from the top of a cliff that is 300 m high.
    1. How long does it take the stone to reach the ground?
    2. How far from the base of the cliff does the stone land?





  2. A golf ball is hit at an angle of 40o with the horizontal. If the initial velocity of the ball is 60 m/s how far will it travel horizontally before it hits the ground?




  3. An object is shot out of a cannon and travels for 20 s until it hits the target 4 km away.
    1. What is the projectiles initial horizontal and initial vertical velocity?
    2. How high did the projectile travel?
    3. What angle does the cannon make with the ground?
    4. What is the projectiles velocity out of the cannon?





  4. A tank fires a shell off the top of a 125 m high hill. The barrel is at an angle of 25 degrees with the horizontal. The shell leaves the barrel at 175 m/s. How far does the shell travel before hitting the ground?




  5. An object having a mass of 125 g is placed on a turntable rotating 20 RPM at a distance of 75 cm from the center. It begins to slide. What is the coefficient of friction between the object and the turntable?




  6. Where must the object in question 5 be placed if the RPM's are increased to 45 RPM?




  7. A block of wood having a mass of 250 grams is placed on a turntable. The coefficient of friction between the turntable and the block is 0.35. When the block is placed 25 cm from the center of the spinning turntable it begins to slide. How fast is the turntable spinning (RPM'S)?




  8. A pendulum 250 cm long has a period of 2.5 s. What is the period of a pendulum in the same location (not necessarily earth) if it has a length of 0.10 m?




  9. A 200 gram object is attached to a 2.5 m long string and swung in a horizontal circle at constant speed of 20.0 m/s. What is the tension in the string?
