You and your friend are standing on level ground 25.0 m apart. They are getting ready to test their tennis ball cannon, which is positioned next to your friend. The cannon is aimed upward at an angle of 50° with respect to the ground and has an adjustable launch speed. a) The cannon fires. Draw a motion diagram for the tennis ball while it is in flight (include several “v” arrows and one “delta v” arrow). b) What launch speed must the cannon be adjusted to so the tennis ball lands where you are standing? Assume air resistance does not significantly affect the flight of the ball.

    A small, spring-loaded cannon launches a tennis ball from level ground with an initial speed vi at an angle θi with the horizontal. The tennis ball lands a horizontal distance R from its launch point. The highest point the tennis ball reaches during its flight is a distance R/12 above the ground. In terms of R and g, find the following. (You may ignore air resistance.) (a) the time interval during which the tennis ball is in motion (b)the tennis...

    Need help With Analysis questions. Ballistic Pendulum Lab In this lab, you will explore conservation of Energy and Momentum in an inelastic collision between a projectile and a cardboard box suspended from a string. In particular, you will see that the transfer of linear momentum is easily accounted for in an inelastic collision, but the transfer of kinetic energy is not easy to measure directly. This is because Kinetic Energy in collisions transfers to vibrational, acoustic, and potential energy. Once...
