A) Estimate the speed in mph with which water comes out of a garden hose using your past observations of water coming out of garden hoses and your knowledge of projectile motion. (Take the inclination angle to be 45o, the initial height to be 1.0 m, and the range of the stream to be 4 m.)
B) A cannonball is fired with initial speed v0 at an angle 30o above the horizontal from a height of 43.3 m above the ground. The projectile strikes the ground with a speed of 1.4v0. Find v0. (Ignore any effects due to air resistance.)
