The metal block m is clamped in a rectangular box with a compressed light spring. Pressure sensors are installed on the upper and lower roof plates of the box. The box can move along the vertical track. When the box moves vertically at a constant deceleration with an acceleration of 6m / S ^ 2, the pressure displayed by the pressure sensor on the upper roof is 6N, and the pressure displayed by the pressure sensor on the lower floor is 10N, What might the vertical motion of the box look like? When the pressure of the upper roof is exactly equal to zero, Mg-F = ma2, the acceleration A2 = - 10 m / S2 is obtained How did you get that?
It's going to the right

- 11. The metal block m is clamped in a rectangular box with compressed light spring, as shown in the figure. The pressure sensors are installed on the top and bottom plates of the box, and the box can move along the vertical track. When the box moves upward with a = 2.0 M / S2 acceleration, the pressure displayed by the sensor on the top plate is 6.0 n, and the pressure displayed by the sensor on the bottom plate is 10.0 n Where can this thing be used in real life? Please give an example
