Terminal velocity is the maximum speed that a body falling through air can reach due to air resistance. terminal velocity is given by the formula y =
. where m is
cpa'
the mass of the falling object, g is acceleration due to gravity ( = 9.81 moters per second ). c is a drag coefficient with 0.5& cs 1.0. p is the density of air ( 1.2
kg/m), and a is the cross-sectional area of the object. suppose that a raindrop falls from the sky. the mass of the raindrop is given by m =
d where r is its radius
and d = 1000 kg/m. the cross-sectional area of the raindrop is a= air
(a) substitute the formulas for the mass and area of a raindrop into the formula for the terminal speed and simplify the expression,

that would be b i just took the test : )

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
