Freefall Problems and Regular Kinematics Problems

Page history last edited by Tolboom 11 years, 5 months ago
  1. An object is dropped. After 15 s how fast is it moving?
  2. A truck is traveling at 11 m/s when the driver slams on the brakes and comes to a halt. If it took her 2 s to come to a halt, what was the acceleration of the truck?
  3. What is the velocity of a tennis ball that is thrown straight up in the air at its maximum height?
  4. If the tennis ball in #3 is in the air for a total of 6 s, when does it reach its maximum height?
  5. What is the height of the tennis ball referenced in #3 and #4?
  6. Benjamin kicks a ball that is initially moving at 2 m/s towards him. The ball ends up going 5 m/s away from him. If the acceleration of the ball was 35 m/s^2, how long was his foot in contact with the ball?
  7. A penny is dropped from the Empire State building which is 381 m tall. Disregarding air resistance, how much time will it take for it to hit the ground? How fast will it be going when it hits?
  8. A hockey puck has an initial velocity of 0.5 m/s and a final velocity of 11 m/s. What distance was it accelerated over, if its acceleration was 13 m/s^2?
  9. A car is dropped from a 30 m tall crane as part of driving demonstration. How fast is the car going when it hits the ground?
  10. A marble rolls to a stop on the carpet. If the marble rolls 6 m in 4.8 s, was was its initial velocity?
