Question

?

Answer 1

I would use equation 3?

Answer 2

yes, solving for delta x

Answer 3

x=v*3.2+(1/2)(9.8)3.2^2

Answer 4

initial velocity is 0 since the rock is just being dropped not thrown

Answer 5

50.18m

Answer 6

good

for b) use the first kinematic equation to find the final velocity

Answer 7

v=0+(9.8)(3.2)

Answer 8

31.36m/s

Answer 9

awesome

for c) do you think the final velocity would be lower or higher w/ air-resistance added to the calculation?

Answer 10

um lower?

Answer 11

good

since the air resistance adds an upward force the net acceleration decreases making the final velocity smaller
