Aball rolling on a skee-ball ramp must be able to rise to the height of the highest-scoring ring if the ball is to have a chance of entering the ring. the ball is released at a height of 0.18 m above the floor and the highest-scoring ring is at a height of 1.05 m above the floor. how fast must the ball be moving upon being released if the ball is to reach the height of the highest-scoring ring?

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
