Aparticle of mass m is projected vertically upward with an initial speed vo in a constant graviational field the particle and α is a positive constant. (a) drag force from the air is proportional to the speed. f -malvl. where v is the velocity of find the maximum height h that the particle will reach in term of g. vo and α (20) (b) let v be the speed of the particle right before it hits the ground. find an equation that relates ur to g. vo and α (an implicit equation is sufficient). (20) (c) find the time the particle spends in the air in terms of g, vo and v does the particle spend more time or less time in the air than it would if it were projected in vacuum?
