4 0

Answer:

40m/s

Explanation:

a=g

u=0

s=81

v²=u²+2as

v²=2(9.81)(81)

v=√1587.6=39.8446985181≈40m/s

two soccer players run toward each other. one player has a mass of 85 kg and runs west with a speed of 8 m/s, while the other ha
marissa [1.9K]

Answer:

Total momentum, p = 55 kg-m/s

Explanation:

It is given that,

Mass of player 1, m₁ = 85 kg

Mass of player 2, m₂ = 105 kg

Speed of player 1, v₁ = -8 m/s (west)

Speed of player 2, v₂ = 7 m/s (east)

Momentum is equal to the product of mass and velocity. For this system, momentum is given by :

p=m_1v_1+m_2v_2

p=85\ kg\times (-8\ m/s)+105\ kg\times 7\ m/s

p = 55 kg-m/s

The total momentum of the system made up of the two players is 55 kg-m/s.

Is it possible for one ray to be shorter in length than another?
8090 [49]
Yes, even light rays can vary in wavelength and frequency, if the length of the ray is sorter, it becomes more energetic and has a higher frequency. If you're talking about a ray tracing diagram for lenses or mirrors, the length of the ray doesn't really matter unless you're finding the path length but there are some procedures for that too. Let me know if I missed what you were asking.
