1 kg is released from height h, 1) In Figure, a block with mass m 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 v= 9 m/s at the point F.(sin45=0.7 g=9.8 m/s?) 11 m. Its path is without
