Mary has a mass of 40 kg and sprints at 1 m/s. How much kinetic energy does she have? ¼
She has a kinetic energy of 20 J.

Roberto has twice the mass his sister Mary has (see above) but runs at the same velocity as Mary.

Will his kinetic energy be twice as much? Show your work.

electrical power

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

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.
