The function​ s(t) represents the position of an object at time t moving along a line. Suppose s (2 )equals 146and s (6 )equals
sineoko [7]

Answer:

v(t) = 27 units

Explanation:

The function s(t) represents the position of an object at time t moving along a line such that,

s(2)=146

and

s(6)=254

We need to find the average velocity of the object over the interval of time [2,6]. The velocity of the object is equal to the total distance divided by time. It is given by :

v(t)=\dfrac{s(6)-s(2)}{6-2}

v(t)=\dfrac{254-146}{6-2}

v(t) = 27 units

So, the  average velocity of the object is 27 units. Hence, this is the required solution.

Two gliders move toward each other on a linear air track, which we assume is frictionless. Glider A has a mass of 0.50 kg, and g
Nataly_w [17]

Answer:

-0.4 m/s

-3.552 m/s

Explanation:

m_1 = Mass of first glider = 0.5 kg

m_2 = Mass of second glider = 0.3 kg

u_1 = Initial Velocity of first glider = 2 m/s

u_2 = Initial Velocity of second glider = -2 m/s

v_1 = Final Velocity of first glider

v_2 = Final Velocity of second glider = 2 m/s

As the linear momentum of the system is conserved we have

m_1u_1+m_2u_2=m_1v_1+m_2v_2\\\Rightarrow v_1=\dfrac{m_1u_1+m_2u_2-m_2v_2}{m_1}\\\Rightarrow v_1=\dfrac{0.5\times 2+0.3\times (-2)-0.3\times 2}{0.5}\\\Rightarrow v_1=-0.4\ m/s

The velocity of glider A is -0.4 m/s

u_1 = 0

u_2 = -5 m/s

v_2 = 0.92 m/s

m_1u_1+m_2u_2=m_1v_1+m_2v_2\\\Rightarrow v_1=\dfrac{m_1u_1+m_2u_2-m_2v_2}{m_1}\\\Rightarrow v_1=\dfrac{0.5\times 0+0.3\times (-5)-0.3\times 0.92}{0.5}\\\Rightarrow v_1=-3.552\ m/s

The velocity of glider A is -3.552 m/s

saw5 [17]

Answer:

Explanation:

The electronic configuration of many ions is that if a closes noble gas to them in a periodic  table.

An Anion is a ion that has gained one or more electron, acquiring a negative charge.

A Cation is a ion that has lost one or more electron, gaining a positive charge.
