Answer:
a= -1.01m/s^2
Explanation:
A) We define all the variables that are given,
In this way
Acceleration = a
[tex]m = 2.0Kg[/tex]
[tex]F = 3.0N[/tex]
We obtain the Normal assuming 5% of the potato reading scale, so
[tex]N = (2 + 2 * 5\%) * 9.8[/tex]
[tex]N = 20.58N[/tex]
We add forces to reach equilibrium, and you get
[tex]N-F-mg = ma[/tex]
** The notation of the symbols is done according to the notation of the graph
So,
[tex]a = \frac {N-F-mg} {m}[/tex]
[tex]a = \frac {20.58-3-2 * 9.8} {2}[/tex]
[tex]a = -1.01m / s ^ 2[/tex]
B) When making pressure it is understood that the shape takes the perpendicular direction of the direction of the force that is performed. If the pressure remains constant, the scale will also increase in its measurement.

Answer:
a) [tex]a=1m/s^2[/tex] downwards
b) The mound will be reduced in height (the acceleration is downwards) and will begin to grow sideways. The reading will remain the same until the spoon reaches the scale surface.
Explanation:
On the mound, the forces acting before the spoon are:
N1 - m*g = 0 Where N1 is equivalent to the reading of the scale.
N1 = 2*10 = 20N
After the spoon starts pressing, this value increases by 5%:
N2 = 20*105% = 21N So, at this point the forces on the moud are:
N2 - m*g - F = m*a Solving for a:
a = -1m/s^2 This result tells us that the center of mass of the potatoes is moving downwards. Since it cannot move because of the scale, it has no other option than to grow sideways as it is pushed.
