A frictiоnless trаck is shоwn in Fig. 4.1 belоw. A block of mаss m = 5 . 00 k g slides down аn incline of height h = 15 . 0 m with an angle of inclination α = 60 . 0 ° . It passes points A, B, C, D, E, A of a circle of radius R = 10 . 0 m before returning to the horizontal track. (a) What minimum speed v 1 , m i n does the block have to start in order for it to complete the circular motion without falling? If the block starts at height h = 15 . 0 m with an initial speed of v 1 , i = 1 . 50 v 1 , m i n , (b) what is the magnitude and direction of the normal force exerted on the block when it is at point C, which is the top of the circle? If the track has a small rough region with coefficient of kinetic friction μ k = 0 . 600 and the length of the region is l = 10 . 0 m , as shown in Fig. 4.2, (c) what minimum speed v 2 , m i n does the block have to start with after releasing from the incline of height h = 15 . 0 m in order for it to complete the circular motion without falling? If the block starts at h = 15 . 0 m with an initial speed of v 2 , i = 1 . 50 v 2 , m i n and goes through the track shown in Fig. 4.2, (d) what are the magnitude and direction of the normal force exerted on the block when it is at point E, which is 60 . 0 ° from the vertical, and (e) what are the magnitude and direction of the block’s tangential acceleration at point E? (Note: Fig. 4.1 is for questions (a) and (b); and Fig. 4.2 is for questions (c), (d), and (e).) fig4_q20.jpg
