= Questions 5-8. The 64.4 lb block begins sliding along the smooth horizontal ft surface with speed v. = 40". At point O, the surface transitions into the vertical curve with radiusr = 100 ft. The surface remains smooth. The arc between point and point A subtends an angle 0 = 30°. 5. Determine the block's speed as it passes point A. b. 27.2 ft a. 49.64 C. 347# ft 177 6. Sketch a free body diagram and an inertial force diagram of the block at the instant it passes over point A. 7. Determine the magnitude of the block's tangential acceleration as it passes point A. ft ft a. 27.9 b. 4.90 얄 6.1 ft c. 8.50 ft d. 16.17 8. Determine the normal force the surface exerts on the block as it passes point A. a. 55.8 lb b. 70.5 lb c. 14.7 lb d. 79.11b
