What forces are acting on a book lying on the table? Are action-reaction forces involved in this situation?

Answers

There is a weight force acting on the book downwards. There is a normal contact force also on the book upwards. These are equal and opposite. These two force are NOT an action-reaction couple (they are different types, they both act on the book)

Physics question WILL GIVE BRAINLIEST!!! A 1,600 kg train car rolling freely on level track at 16 m/s bumps into a 1.0 x 10^3 kg train car moving at 10.0 m/s in the same direction, and the two latch onto each other and continue together. What is their final speed?10 m/s
14 m/s
6.0 m/s
16 m/s

Answers

Answer:

v'\approx 14\ m/s

Explanation:

Linear Momentum

Two objects of masses and moving in a linear path at speeds and respectively have a total momentum of

p=m_1v_1+m_2v_2

When the objects collide, a change of conditions occurs and they start to move at different speeds. The necessary condition to find the after-colliding speeds is the conservation of linear momentum that states the total momentum of an isolated system doesn't change regardless of the internal interactions of the objects. Thus, the new momentum is

p'=m_1v_1'+m_2v_2'

And they must be the same, thus

m_1v_1'+m_2v_2'=m_1v_1+m_2v_2

We know both cars stick together after the collision, so the final speed is common to both, and the above formula becomes

(m_1+m_2)v'=m_1v_1+m_2v_2

Solving for v'

\displaystyle v'=(m_1v_1+m_2v_2)/((m_1+m_2))

Plugging in the values, we have

\displaystyle v'=((1600)(16)+(1000)(10))/((1600+1000))

\boxed{v'=13.69\ m/s}

Correct option (closest to the computed speed): 14 m/s

What is the exact time of a full earth rotation?

Answers

Partyrockchickk is on the right track,but 23:56:04 is not exactly exact.
23h 56m 4.0906s is closer, but stillnot exact. You'll never see an 'exact'
number written anywhere. Firstbecause it doesn't work out to an exact
decimal of anything, and secondbecause it changes ! The Good Friday
earthquake in Alaska changed it,the Fukushima earthquake changed it,
the Nepal earthquake changed it,and the daily drag of the tides changes
it by something like 0.001second every century.

One thing's for sure:  It is definitely not 24 hours.
The exact time is  23 hours, 56 minutes, and 4 seconds. hope this helps hun
