In the previous part, you discovered that the trajectory of an object does not depend on the object's size or mass. but if you have ever seen a parachutist or a feather falling, you know this isn't really true. that is because we have been neglecting air resistance, and we will now study its effects here. select air resistance for the simulation. fire a baseball with an initial speed of roughly 20 m/s and an angle of 45∘. compare the trajectory to the case without air resistance. how do the trajectories differ?
