H.W-5 Water is sprayed at an angle of 90° from the slope at 20 m/s. Determine the range R. R <- 20 m/s

1. A Projectile with a muzzle velocity of 550 m/sec is fired from a gun on top of a cliff 460 m above sea level. If the projectile hits the ocean surface 49.2 seconds after being fired, determine: Draw the figure properly. No figure no point. a. The angle of elevation of the gun; b. The range c. The highest point attained above the cliff. y V, H water surface (w.s.) R

2. An airplane flying N30° W at 150 km/h encounters a wind blowing E5 N at 40 km/h. Determine the resultant ground velocity of the plane. Include a vector diagram in your solution.

1110. In Fig. P-1109, a ball thrown down the incline strikes it at a distance s 254.5 It. If the ball rises to a maximum height h 64.4 ft above the point of release, compute its initial velocity vo and inclination 6. Ans. v. = 80.5 ft per see; 0= 53.1° FIG. P-1109 and P-1110.
