Consider a 15\": cannonball that is shot out of a cannon at an angle of 30" with an initial speed of 250ftf's. The cannonball is launched from at ground, and lands at the same elevation as it was launched. a. What is the initial kinetic energy of the cannonball, in Joules? b. What is the maximum height of the projectile {Use energy argument]? c. What is the potential energy at the maximum height? d. What is the kinetic energy at the maximum height? e. Using energy equations/arguments, derive an expression for the speed in terms of height 15'. h. Sketch your function, using proper labels on the axis
