You may treat it as an explosion that doesn't add kinetic energy to the two masses, so the treatment doesn't buy you much. Remeber that in a spring-mass system the acceleration is proportional to the displacement from the equilibrium position, the constant of proportionality being ##\omega^2##. What are the equilibrium position and ##\omega## after the string is burned and the copper sphere drops?Josielle Abdilla said:I am revising the laws of motion and momentum.

Do you have any ideas about this pls?
Do you have a reason for thinking this answer is wrong?Josielle Abdilla said:I can't think of how is it possible for the copper sphere to adopt an acceleration other than 10m/s. Do you have any ideas about this pls?
It cannot be that since m/s does not express an acceleration.Josielle Abdilla said:an acceleration other than 10m/s
The formula for acceleration is a = (v - u) / t, where "a" represents acceleration, "v" represents final velocity, "u" represents initial velocity, and "t" represents time.
According to Newton's Second Law of Motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This means that a larger mass will require a larger force to achieve the same acceleration as a smaller mass.
When the thread snaps, it means that the force holding the masses together is no longer present. This results in the masses moving independently, and their acceleration will be determined by the net force acting on each mass.
To calculate the net force, you need to know the mass of each object and the force acting on it. You can then use Newton's Second Law (F = ma) to calculate the net force acting on each mass, which will determine their acceleration.
Yes, the acceleration of each mass can be different at the instant the thread snaps. This is because the net force acting on each mass may be different, leading to different accelerations according to Newton's Second Law.
