A spring is compressed between two blocks, one with a mass of 2 kg and the other with a mass of 3 kg. If the 2 kg block has an average acceleration of 6 m/s^2 when the spring acts on it, what will be the average acceleration of the 3 kg block???

Respuesta :

Answer:

2=6

3=9

Explanation:

I think this is right I'm not sure but I have done problems like this and did based on what I remember.

The average acceleration of the 3 kg block is 4 m/s².

The given parameters;

  • mass of first block = 2 kg
  • mass of second block = 3 kg
  • acceleration of the first block, = 6 m/s/s

According to Newton's third law of motion, action and reaction are equal and opposite.

The force exerted on both blocks are equal and opposite.

[tex]F = ma\\\\m_1 a_1 = m_2a_2\\\\a_2 = \frac{m_1 a_1}{m_2}\\\\a _2 = \frac{2\times 6}{3} \\\\a_2 = 4 \ m/s^2[/tex]

Thus, the average acceleration of the 3 kg block is 4 m/s².
