When a particle of mass m is at (x, 0), it is attracted toward the origin with a force whose magnitude is k x 2 If the particle starts from rest at x b and is acted on by no other forces, find the work done on it by the time it reaches x a, 0 a b ...

ANSWER To find the work done on the particle by the time it reaches x a we can use the workenergy theorem which states that the net work done on a par ...

Question:

When a particle of mass m is at (x, 0), it is attracted toward the origin with a force whose magnitude is k/x². If the particle starts from rest at x = b and is acted on by no other forces, find the work done on it by the time it reaches x = a, 0 < a < b.
