14. A rocket is shot up into the air and then comes back down and hits the ground 9.2 second later.
sineoko [7]

Answer:

105.8 m

46 m/s

Explanation:

From the time the rocket is launched to the time it reaches its maximum height:

v = 0 m/s

a = -10 m/s²

t = 9.2 s / 2 = 4.6 s

Find: Δy and v₀

Δy = vt − ½ at²

Δy = (0 m/s) (4.6 s) − ½ (-10 m/s²) (4.6 s)²

Δy = 105.8 m

v = at + v₀

0 m/s = (-10 m/s²) (4.6 s) + v₀

v₀ = 46 m/s

MAVERICK [17]

A textbook would hit the ground first


Factors:

-Textbook weighs most

-Pillow is flat and fluffy not very aerodynamic) also is very light

-Paper airplane will glide to the ground do to its wings and will hit the ground last

A father is pulling his child on a sled in the snow. According to Newton’s Third Law, the force the father exerts on the sled is
viktelen [127]
That is because there are other forces like the friction forces that apply differently on both of them. The frictional forces applied to the sled are smaller than they are on the father, for example, so it's possible for him to pull it.

A person pushes two boxes with a horizontal force F of magnitude of 100 N.
Monica [59]

The magnitude of the action–reaction pair between the two boxes (A and B) will be "18.2 N".

According to the question,

Mass of box A,

  • m_A = 9\  kg

Mass of box B,

  • m_B = 2 \ kg

Horizontal force,

  • F_{app} = 100 \ N

From the Newton's law,

→ F_{app} = (\frac{F_{app}}{m_A+m_B} )a

or,

→      a = \frac{F_{app}}{(m_A+m_B)}

Bu substituting the values, we get

→         = \frac{100}{9+2}

→         = \frac{100}{11}

→         9.10 \ m/s^2

We can see that between the two boxes, the action-reaction pair exist.

then,

→ F_{action-reaction} = m_b \ a

→                          =2\times 9.10

→                          = 18.2 \ N (magnitude)

Thus the above solution is appropriate.
