<span>Throwing the bowling ball would have the greatest negative velocity becasue Principle of the Conservation of Momentum states that: if objects collide, the total momentum before the collision is the same as the total momentum after the collision (provided that no external forces - for example, friction - act on the system). That’s amazingly useful because it means that you can tell what is going to happen after a collision before it has taken place. Principle of Conservation of Energy: Of course, energy is also conserved in any collision, but it isn't always conserved in the form of kinetic energy.</span>
In linear motion , when a body moves with uniform velocity , in time t , its linear displacement will be ;
S = r∅ S = vt
r∅ = vt
r.∅ / t = v
As
v = rw
where ∅ = 90° is the angle between between radius vector r and angular velocity w (omega )
In case ∅ ≠ 90° , we can write v = r w sin∅
It gives us v = w× r

This question is incomplete
Explanation:
The completed question is in the attachment to this question
The two objects (X and Y) at rest had a potential energy of Mx.gH and My.gH respectively because the formula for potential energy (P.E) is mgh. Where m is the mass of the object, g is acceleration due to gravity and h is the height of the object above the ground. Hence, Mx and My are the masses of X and Y respectively.
The change in there potential energy to kinetic energy and back to there potential energy will be
P.E of Y - P.E of X (because mass of Y is larger and will hit the floor first)
Hence, My.gH - Mx.gH ⇔ (My - Mx)gH
Correct option is C
