Calculating Force Generated by Person

[timorito]

Homework Statement

A object has a mass of .37kg starts at rest in a persons hand.The person then accelerates the object at a constant rate straight up in the positive y direction over a displacement of 1.9 meters. The object is then released and travels to a maximum height of 28.7 meters.. What force was generated by the person while the object was in his hand? Answer in Newtons. ( note: when the object is in the persons hand, ignore the weight force,- just consider the only force on the object is supplied by the person)

I need someone to please show me the steps because my quiz is similar and have no idea where to begin.. I would appreciate steps and reasoning. Thanks
