Answer:

The answer to your question is below

Explanation:

Data

m = 3 kg

vo = 6 m/s

vf = -8 m/s

Process

a= Initial kinetic energy

    Eko = (1/2)mv²

    Eko = (1/2)(3)(6)²

    Eko = 54 J

b) Final kinetic energy

    Eko = (1/2)(3)(-8)²

    Eko = 96 J

c) Initial momentum

   pi = (3)(6)

   pi = 18 kg m/s

d) Final momentum

   pf = (3)(-8)

   pf = -24 kg m/s

what is the main reason that attitudes are more often revealed in spoken rather than written language
pishuonlain [190]
It's a combination of all those things. probably because we are taught from an early age to write in an academic fashion, giving balanced arguments and a conclusion. When speaking from the heart, there is no opposing argument nor is there a conclusion, just emotion.

When a net force of 17.0 newtons is applied to a dictionary placed on a frictionless table, it accelerates by 3.75 meters/second
4vir4ik [10]
Force = (mass) x (acceleration)    (Newton's second law of motion)

Divide both sides of the equation by 'acceleration', and you have

Mass = (force) / (acceleration)

Mass = 17 newtons / 3.75 meters per second-sqrd = 4.533 kilograms (rounded)
