Anyone? Please, I just need a sketch of the forces applied to the particle and the chain. :'(

1. A particle of mass m is tied on one end of a very long chain which has a linear density μ (kg/m) and lies on a surface with the chain wound next to it. The particle is thrown upwards with an initial velocity V. Find the maximum height the particle is going to reach. My question is not what...

Yeah, I took Yduck = h. My final result is that V0min = sqrt(v2 + 2gh) but the book says the answer is V0min = sqrt(v2 + 0.5gh)

1. A duck flies horizontally with velocity v at a height h. When a duckhunter is right below it, he shoots with his shotgun. What is the minimum initial velocity V0 of the bullet and the angle a at which he shoots so that the bullet hits the duck? Obviously, given are v, h and gravity...
