... conservation of energy can be used. Since it cannot be used for the impact (why?), it is applied just after the impact. In order to roll over the bump, the wheel must go to position 3 from 2. When (vG)2 is a minimum, (vG)3 is zero. Why? Energy conservation equation : T2 + V2 = T3 + V3 {½ (10) (vG)22 ...
