Answer 1

12. The angle between two forces 1700 N and 2500 N is 37° when placed tail to tail. What is the magnitude of the resultant force? F = VER+62+2 fifacoso = V1700+2500l 2.1700. 3500.COS 37 F = 2351598.165 f = 1533.49 N 9. The blades of a wind turbine are 116 feet long. The propeller rotates at 15 revolutions per minute. (a) Find the angular velocity of the propeller in radians/sec. r=116 f-15 rpm w = 2 af =20(15) w=300 radimios = 300 radlsea = 1.5708 radlser (b) Find the linear velocity of the tips of the blades. Round your answers to four significant digits. v=rw=116.30ī = 116.301 =585 rad (sec ~ 182.2124 Gad/sec 45= 3.14159}
