An object is dropped from a height of 78.7 m above ground level. (Assume air resistance is negligible.) (a) Determine the distance (in m) traveled during the first second. m (b) Determine the final velocity (in m/s) at which the object hits the ground. (Enter the magnitude.) m/s (c) Determine the distance (in m) traveled during the last second of motion before hitting the ground. m
