Vertical Motion and Free Fall
4PRACTICE PROBLEM
During a voluntary vertical take-off, a dronefly of mass 20 g produces a constant acceleration by flipping its wings for 1.2 s. At t = 1.2 s, the dronefly stops flipping its wings, and 0.2 s later, it is 3.2 m above the take-off level. Calculate the acceleration produced during the first 1.2 s.
