A stone is dropped into a river from a bridge 40m above the water surface. Which of the following can be said about the stone as it lands?
A. it fell for 8.2 s
B. Its velocity is -37 m/s
C. Its acceleration is -13m/s/s
D. its speed is 28m/s
(we ignore air resistance for now, so acceleration for vertical motion Is simply -9.8)
that being said i know c is incorrect
