The original price of a washing machine is 1450 yuan. Now it is sold at a 20% discount, but the price is still higher than the cost. 19. How much is the cost of this washing machine?

1450 × (1-20%) / (1 + 19), = 1450 × 0.8 × 910, = 1044 yuan. A: the cost of this washing machine is 1044 yuan

2. As shown in the figure, when the board with length of L = 2M and mass of M = 8kg is placed on the horizontal ground, and the speed of the board moving to the right is v = 6m / s, a small block with mass of M = 2kg regardless of size is gently placed at the front end of the board. The dynamic friction coefficient between the board and the ground and between the block and the board is μ = 0.2, g = 10m / S2 (1) The acceleration of the block and the board; (2) the speed of the block sliding away from the board

5. As shown in the figure, in the experiment of studying friction, a small wooden block placed on the horizontal table is pulled horizontally with a spring scale each time, and the reading of the small wooden block's movement is shown in the following table (the contact surface between the wooden block and the table is the same each time): then from the table, we can see () & nbsp; the number of experiments, the movement state of the small wooden block, and the reading of the spring scale (n) 1 static 0.4 2 static 0.6 3 Acceleration 0.7 4 constant speed 0.5 5 deceleration 0.3 A. The maximum friction force on the block is 0.7nb. The maximum static friction force on the block may be 0.5nc. In the five experiments, the friction force on the block is the same three times.
