III. In the following figure, a device is used to do some demonstrations. On the left side, there is a horizontal surface and a ramp made from the same materials, both surfaces provide friction force. On the right hand side there is a smooth metal track and the friction on the track can be neglected. A solid ball of mass 0.500 kg and radius 4.00 cm rolls smoothly (pure rolling) with a horizontal linear speed v along the left horizontal surface before climbing onto the ramp. The top of the ramp is h meters above the horizontal surface. The ball barely reaches the top of the ramp (the velocity is zero at the top) then passes the top and starts to slide down (pure sliding) hits another identical ball which is at rest on the horizontal part of the track. If the speed of the second ball after collision is 10.0 m/s, what is the initial linear speed of the first ball? 2m₁ Note: Formulas for two objects collision are: v₁ = M₁-M₂ M₁+M₂ V₁ and v₂ = V₁: M₁+m₂ the rotational inertia of a solid ball is Mr and take g =10.0 m/s². Mr² no frition 0-V
