1. The problem statement, all variables and given/known data A body is fired vertically upwards with an initial velocity of 100m/s. (a) how far will it rise (b) how long will it take to reach maximum height? (c) what is the time taken before it strikes the ground again. (d) what is the velocity at impact 2. Relevant equations s= ut v= u+at s=ut + 0.5*at^2 v^2=u^2+2as 3. The attempt at a solution I can't even start it, i've got no idea, it doesn't seem that the question is even giving me enough information.
