Karen drops a 2.0 kg rock from the top of a mountain. Determine the distance the rock travels after falling for 3 seconds assuming it has reached free fall and given the gravitational acceleration of 9.8 m/sec^2 downward. [HINT: Distance=(0.5)*(acceleration)*(time^2)]


What can we say about Karen’s rock as it falls?
a) The rock has a constant velocity
b) The rock has an acceleration of -9.8m/s2
c) The rock accelerates for the 1st second and decelerates
