Momentum problem,please check!! 1. The problem statement, all variables and given/known data A 0.2 kg object is thrown vertically upwards at an initial velocity of 20m/s.Find its momentum when : a) it reaches its maximum height b) its momentum at the halfway of its maximum height 2. Relevant equations P=vm V^2=Vo^2+2gh 3. The attempt at a solution When it reaches its maximum height does it final velocity equal to zero? If it is like this it will be the momentum also zero. And for the halfway the answer should be 5sqrt(2),but I don't know how can I get it.
