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?
