If a 2 kg block has an average acceleration of 6 m/s2 when the spring acts on it what will be the average acceleration of the 3 kg block

The average acceleration of the 3 kg block, a = 4 m/s²

Explanation:

Given data,

The mass of the block, m = 2 kg

The average acceleration of the block, a = 6 m/s²

Therefore, the force exerted by the spring on the mass,

                                           F = m x a

                                              = 2 x 6

                                              = 12 N

Therefore, the force of the spring, F = 12 N

When a block of mass 3 kg is attached with the spring, the acceleration of the spring will be,

                                   a = F / m

                                      = 12 / 3

                                      = 4 m/s²

Hence, the average acceleration of the 3 kg block, a = 4 m/s²
