A penny is dropped from the Statue of Liberty a. what is the velocity of the penny after 0.30 seconds

b. How far did the penny drop after 0.30 seconds

a) The velocity is 2.94m/s

b) 0.441

Explanation:

a) Assume gravity is 9.8m/s^2

Use the equation below to solve for the velocity at 0.30 seconds

,

vf =unknown velocity  vi= initial velocity vi=0m/s  a= 9.8m/s^2 t=0.30seconds

Step 1: Substitute the variables with the knowns

Step 2: Solve

b)

Use the equation below to solve for the displacement at 0.30 seconds

Step 1: Substitute the same variables with the knowns

Note that vi*t=0 as vi=0m/s

Step 2: Solve

x=0.441m

d.7.5cm is your answer
