A rock is thrown straight down with an initial velocity of 14 m/s from a cliff. What is the rock’s

displacement after 2.0 s?

2 answers

after 2.0 s the rock has been accelerated by gravity ... vf = 14 + (2 * g) m/s

the average velocity is ... (vi + vf) / 2

displacement is ... (average velocity) * time
