A simple way for me to understand is to sketch the velocity time graph. Area under the graph will give you the displacement. All the formulas can be derived from the graph and it should help you in understanding, it helped me when I started learning too. And it saves you a lot of time thinking...

For part b, highest point should be when velocity drops to 0 due to gravity, hence v = 0. unless they are asking for maximum velocity. If so, for part c, acceleration will be due to gravity, as there is no upward thrust part e, find the maximum height first, that would be the distance the...

I would work out the energy gain in kinetic energy = loss in gravitational potential energy (1/2)(m)(v^2) = (m)(g)(h) simplifying you get v^2 = 2(g)h h = (121)/(2g)
