A painter accidentally drops a can of paint from a high scaffold. How far has the can fallen after 4.0 s?

a. - 50 m

b. - 112 m

c. - 78 m

d. - 27 m

We are asked to determine the height of falling after a can of paint is dropped after 4 seconds. We use the free-fall equation that is y = vot - 1/2 gt2 where vo is zero and g is equal to 9.8 m/s2. Upon substituting t with 4 seconds, y is equal to - 78.4 m. ANswer is C.
