    An object is place against a compressed spring at the bottom of an air track that slope upward at an angle 30. When the spring is release, find at which position, the object leave the spring?
    Given: the spring is compressed A, the spring constant is k, m is mass of object, mass of spring is negligible

    The problem is that, after the object releases from the spring, it will accelerate.. if the velocity of object is greater than spring, the object will leave. but when?

    Initially the ball accelerates with the spring as it loses its potential energy , till the point , the spring passes its mean position and starts gaining the potential energy, but the ball remains in motion it had gained . Work on it.
