A estimate the speed in mph with which water comes out of a, Ask an Expert

Academics

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 45^o, 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 30^o 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.)
