A brick falls freely from a high scaffold.

A. What is its velocity after 4.0s?

B. How far does the brick fall during the first 4.0s?

I don't know what formula to use. I only have time, and I guess the first velocity would be 0s.

1 answer

finalvelocity=initialvelocity + g*time
g= 9.8m/s^2

for how far, see your other post.
