Answer:
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
