A student performs an experiment to determine the distance moved and velocity of a projectile as a function of time. A 1.00-kg object is initially at rest. The student applies a force of 19.6 N through a distance of 0.50 m to propel the object straight upward. It has an initial speed v and reaches a peak height h above the launch point. What is the average acceleration of the object from rest to v?
