1.A cylinder rolls without slipping on a horizontal plane and then up an incline. The linear speed of the cylinder at the beginning is v. What maximal height h will the cylinder reach?
2.Helicopter of mass M holds stationary in the air fires a missile of mass m<< M with a speed v. Find the recoil speed of the helicopter.
0= Mv + mu
Mv/m = Mu/m
