need some help? read sections 2.5-2.6
In all of these problems, an object is "falling freely" which means we ignore air resistance.
Since it is falling, the acceleration due to gravity = 9.8 m/s/s. Any time we do labs, we'll want to use this acceleration. When we do problems, we want to focus on concepts more than exact numbers, so its okay to round this up to 10 m/s/s.
