Physics

  1. The spring of a toy gun has a force constant of k = 533N/m and negligible mass. The spring is compressed the length of thegun barrel, 7.25 cm, and a 0.168-g ball is placed against thecompressed spring. A constant frictional force of 5.45-N acts onthe ball as it travels through the barrel. The ball leaves thebarrel at the moment that it loses contact with the spring. The toygun is ‘fired’ at a height of 1.33-m above the ground. Ignore airresistance.

  1. Show how to determine the speed of the ball as it leavesthe barrel when the toy gun is oriented horizontally.

  2. Show how to determine the distance that the ball travelshorizontally, and its speed of impact.

  3. Show how to determine the speed of the ball as it leavesthe barrel when the toy gun is oriented vertically.

  4. Show how to determine the maximum height attained by theball, and the speed of its impact when it lands on theground.
