Water from a fire hose is directed toward a building as shown in the figure below. The water leaves the hose at a speed of vi = 40.0 m/s and at an angle of θi = 42.0° above the horizontal. The base of the hose (at ground level) is a horizontal distance d = 51.0 m away from the building. Find the height h (in m) where the water strikes the building.

MULTIPLE CHOICE, Show your work in the space provided, Circle the correct answer 1. An object is moving with constant non-zero velocity. Which of the following statements about it must be true? As shown in the figure, a woman is straining to lift a large crate, but without success because it is too heavy. We denote the forces on the crate as follows: P is the magnitude of the upward force being exerted on the crate by the person, C...

A 2.70 kg box is moving to the right with speed 8.50 m/s on a horizontal, frictionless surface. At t = 0 a horizontal force is applied to the box. The force is directed to the left and has magnitude F(t)=( 6.00 N/s2 )t ^2 What distance does the box move from its position at t=0 before its speed is reduced to zero? Express your answer with the appropriate units. If the force continues to be applied, what is the...

A couple of problems I was struggling with on my previous assignment 3. A fire dancer in china town makes circles with a ball on a string that is 25cm long. The amount of rotations the fireball makes count it to be 4 times every second. a. Find the speed and acceleration of the fireball. The dancer lets go of the string and the ball shoots into the air straight at you with an angle of 35 degrees to the...

From theoretical considerations, it is suspected that the rate of flow from a fire hose is proportional to some power of the pressure at the nozzle. Do the following data confirm this observation? Get the least-squares values for the exponent and the proportionality factor Q1. Flow Rate 94 118 147 180 230 Pressure 10 16 25 40 60 These data represent solubility of n-butane in liquid anhydrous hydrofluoric acid. Fit...

Your answer is partially correct. Try again A spring is resting vertically on a table. A small box is dropped onto the top of the spring and compresses it. Suppose the spring has a spring constant of 250 N/m and the box has a mass of 1.7 kg. The speed of the box just before it makes contact with the spring is 0.43 m/s. (a) Determine the magnitude of the spring's displacement at an instant when the...
