You might be able to do it with just the kinematic equations,
you know: u,a,s, and want to find v....so you have/want 4 of the 5 variables so yep the kinematic equations can be used here. Do you know what they are?

A boulder with a mass of 2,500kg on a ledge 200m above the ground falls. What is the speed of the boulder just before it hits the ground.
To find velocity you need to use the kinetic energy formula right? But when I tried to plug in everything, it wouldn't work. IT only looks as if the GPE formula would work... could someone help me please?
