Use this information to answer the next 2 questions: a 0.32 kg ball is thrown with a speed of 11.5 m/s. 18. how much kinetic energy does the ball have? 42.3 j 1.84 j 35.9 j 21.2 j 19. how much work would be needed to stop the ball?

Given:

m = 0.32 kg

v = 11.5 m/s

To find:

1) Kinetic energy = ?

2) Work needed to stop the ball = ?

Formula used:

1) Kinetic energy =

2) Work = kinetic energy

Solution:

1)

Kinetic energy is given by,

Kinetic energy =

K.E. =

K.E. = 21.16 Joule

Thus, option (d) is the correct answer.

2)

Work needed to stop the ball is same as the kinetic energy because energy is the capacity to do work. Since, work is opposing the movement of the ball. Thus, Work = - Kinetic energy

Work = -21.16 Joule

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.

that would be because of both gravity and friction. so     c
