In this question use g=9.81. A small stone is projected vertically upwards from the top of a cliff, with speed u . It hits the ground with a speed of 18.2 . A second small stone is also projected vertically upwards with speed u from a nearby cliff which is 4.5m higher. It takes 2.97s to hit the ground. Find the value of u and the height of the first cliff

A sketch and writing down the known/relevant suvat variables and equations is always a good place to start. What are you stuck with?
