Question

(8%) Problem 6: Water leaves a fireman's hose (held near the ground) with an initial velocity vo= 10.5 m/s at an angle = 27.5° above horizontal. Assume the water acts as a projectile that moves without air resistance. Use a Cartesian coordinate system with the origin at the hose nozzle position ©theexpert ta.com 50% Part (a) Using vo, , and g, write an expression for the time, tmax, the water travels to reach its maximum vertical height 50% Part (b) At what horizontal distance d from the building base, where should the fireman place the hose for the water to reach its maximum height as it strikes the building? Express this distance, d, in terms of v0.0, and g d = | v02 sin() 2/2 gl Grade Summary Deductions Potential 10% 90% cos() sin() cos() sin() cos(0) sin() ( ^ Submissions Attempts remaining: 4 (10% per attempt) detailed view 7 89 HOME 456 . 10% 0 END Vo V BACKSPACE DEL CLEAR

Explanation / Answer

Part b)

The answer must be half of the horizontal Range ,R

We know R=(V02 Sin2)/g

We want X=R/2= (V02Sin2)/2g

U typed sin × 2....that becomes 2Sin...which is wrong...
