Answer:

The speed of the man is 0.302m/s in the opposite direction.

Explanation:

We need to apply the theorem of linear momentum:

m1*vo1+m2*vo2=m1*vf1+m2*vf2

The instant before the man throws the book the velocity is zero:

86.6kg*(0)+2.40kg(0)=86.6kg*vf1+2.40kg*(10.9m/s)\\\\vf1=\frac{-2.40kg*(10.9m/s)}{86.6kg}\\vf1=-0.302m/s

Degger [83]

Yes, it's true.

But 2nd Newton Law always come to play when the horse is to move forward because obviously the forces interact antagonistically and mass has to be accounted for.

That's what I think. Hope it's right, all the best.

What is accurate about the planet’s climate system?
ElenaW [278]

The accurate about the planet’s climate system is the wind

because heating near the equator blows the wind to drive the convection cells in the atmosphere, and the friction created by the rotation of the spherical planet in the atmosphere causes the wind to appear to bend left or right across the surface of the planet. ..

The climate system is a highly complex global system consisting of five major components: the atmosphere, the ocean, the cryosphere (cryosphere), the land surface, the biosphere, and the interactions between them.

Solar energy drives the climate by heating the surface of the earth unevenly. Ice also reflects incoming sunlight, further cooling the poles. Temperature differences move the ocean and atmosphere as they work together to disperse heat throughout the globe.
