A giant platform that is connected to a spring, which can propel a person to the cliff above. If a man (85.0 kg) steps onto the platform, it can launch him up along the dotted path. Before it launches, what would be the spring constant in the spring if it compresses 232 cm from his weight and is able to propel him vertically until he just reaches the height of the cliff (10.0 m)? This problem will require Newton's 2nd Law and Kinematics before leaving the spring AND Kinematics after leaving the spring. I would recommend starting with the ending motion (after spring to cliff height) to find how fast you left the spring and continue working backwards.
