A yellow ball with a mass of 2 kg is rolling across the floor at 3 m/s. A red ball with a mass of 3 kg is rolling across the same floor at 3 m/s. Which ball has greater kinetic energy, and why? The yellow ball has greater kinetic energy, because it is rolling at a higher position above the ground.
The red ball has greater kinetic energy, because it has a greater mass.
The yellow ball has greater kinetic energy, because it is rolling at a greater speed.
The red ball has greater kinetic energy, because it is releasing more thermal energy.

The red ball has a greater KE because it has a greater mass.

Explanation:

The formula for calculating Kinetic energy is 1/2(mv^2) (speed can be used for velocity)

so, the yellow ball will be 1/2(2*3^2=1/2(2*9)=18/2=9J

the red ball will be 1/2(3*3^2)=1/2(3*9)=27/2=13.5J

Since the red ball has more Joules of energy, it has more KE.

Hope this helps!

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
