a 91.5 kg football player running east at 3.73 m/s tackles a 63.5 kg player running east at 3.09 m/s. what is their velocity aft
Lesechka [4]

The final velocity is 3.47 m/s east

Explanation:

We can solve this problem by using the law of conservation of momentum. In fact, the total momentum of the two players before and after the collision must be conserved:

p_i = p_f\\m_1 u_1 + m_2 u_2 = (m_1+m_2)v

where:

m_1 = 91.5 kg is the mass of the first player

u_1 = 3.73 m/s is the initial velocity of the first player (we take east as positive direction)

m_2 = 63.5 kg is the mass of the second player

u_2 = 3.09 m/s is the initial velocity of the second player

v is their final combined velocity after the collision

Re-arranging the equation and substituting the values, we find:

v = \frac{m_1 u_1+m_2 u_2}{m_1+m_2}=\frac{(91.5)(3.73)+(63.5)(3.09)}{91.5+63.5}=3.47 m/s

So, their velocity afterwards is 3.47 m/s east.

Most weather occurs in which atmospheric layers?
Slav-nsk [51]

Answer:

Troposphere

Explanation:

The troposphere is the lowest layer of the Earth's atmosphere. The earth's atmosphere has the following layers:

- Troposphere - Stratosphere - Mesosphere -Thermosphere - Exosphere

The troposphere lies 10 km above the land surface and most weather phenomena and conditions (e. g. clouds, turbulence) occur there.

Most of the water vapor in the atmosphere is in the troposphere (about 99%) and most of the atmosphere's mass is contained in the troposphere (75%)

If an element has 7 electrons how many of them will be in the 2nd energy level
inna [77]
Well first you can not go to the 2nd energy level without the first so the first takes up 2 electrons leaving you 5 electrons and the recommended amount is 8 electrons so you would have 5 electrons left
