Objects in vertical motion are an illustration of non-uniform motion. At the peak of the circle, centripetal force is balanced by the object's weight. Therefore, the minimum speed required at this top point is given by v = 
= 
= 5.23 m/s. As the sphere descends from the top to the bottom of the circle, according to the law of conservation of energy, potential energy can be expressed as 
where u is the velocity at the lowest point. Consequently, the modified equation is
=
=
= 11.71 m/s. The collision of the dart with the bullet is an inelastic one. According to the conservation of momentum: v =
=
=
= 58.55 m/s. Thus, the dart's minimum initial speed for the combined system to complete a circular loop post-collision is 58.55 m/s.
Hypothesis: An increase in voltage should result in a corresponding rise in current because according to Ohm's Law,
Ohm's Law indicates that current is proportional to voltage when resistance remains constant. Hence, if resistance stays the same, elevating the voltage will lead to an increase in current. Conversely, if voltage remains unchanged and resistance increases, current will decrease.
