Answer:
bobby has a greater magnitude of velocity because because when angular speed is constant linear velocity is proportional to radius of the circular path
B. They both have same magnitude of angular velocity since the angular speed of the merrygoround is constant
C. Also they both have the same tangential acceleration because the angular speed is constant and tangential is zero for both of them
D. Centripetal acceleration of Bobby is greater
E.they both have the same angular acceleration because angular Speed I constant so angular acceleration is zero for both
Net force is an unbalanced force, so the object will change speed or direction.
Either the object may speed up or slow down.
´To develop this problem we will use the concepts related to the conservation of momentum and the application of energy conservation equations to find the velocity of the mass after the collision, like this:
Velocity of the mass
just before the collision



Therefore the momentum just before collision would be

Momentum after the collision

Since the momentum is conserved we have that



The velocity of mass
after the collision is given by



Therefore the change in momentum of mass 2 is



Therefore the impulse acting on m2 during the collision between the two boxes is 
In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants. When a new substance is formed, the change is called a chemical change.
