1) In Figure, a block with mass m = 1 kg is released from height h, = 11 m. Its path is without friction until it reaches the path with first length d,= 3 m, where the friction force between B and C is f. 9 N, and until it reaches the path, where the friction force between E and F is f,= 7 N. The height is h = 1 m, and second horizontal length is d= 1 m. The block continues its motion after the point F. (a) Find the velocity at the point A. (b) Find the velocity at the point D. (c) Find the height h if the velocity of m is v9 m/s at the point F.(sin45-0.7 g-9.8 m/s) h = 11 m m AB d = 3 m E h, 1 m d, 1 m 45 F h 1) In Figure, a block with mass m = 1 kg is released from height h, = 11 m.
