Askater of mass 40 kg is carrying a box of mass 5 kg. the skater has a speed of 5 m/s with respect to the floor and is gliding without any friction on a smooth surface. a. find the momentum of the box with respect to the floor. b. find the momentum of the box with respect to the floor after she puts the box down on the frictionless skating surface.

For the part a) we need only the momentum of the box and we have the data to find it.

Momentum is given by,

where clearly, p is the momentum, m the mass of the box and v is the velocity.

Substituting,

For part b) we need an analysis of the situation. We understand that the box on a surface that has no friction will continue to rotate at the same speed previously defined. The box can only stop with friction, so,

It is the same that part a)

i would say the answer is food.

hope this !

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.
