<u><em>heyaaaaa</em></u>

<u><em>Momentum before Pb = momentum after Pa</em></u>

Pb = 75*6 - 100*8 = -350kgm/s = Pa = (75+100)V where V is the velocity of the combined mass of the two players after the collision.

<u><em>Velocity has magnitude (speed) and direction. V = -350/175 = -2m/s </em></u>

So the two players are moving at 2m/s in the direction the 100kg player was moving before the collision.

<em><u>I arbitrarily chose the direction of the smaller player as positive so the opposite direction (of the larger player) had to be negative. </u></em>

hope it helpssss!!!!!!

Describe what happens to the particles of a liquid, in terms of movement and kinetic energy, as it is cooled to its freezing poi
nataly862011 [7]
As a system is cooled to its freezing point, the kinetic energy of the particles in the system will lower so the movement are much slower. Cooling means taking out heat from the system. This process is a physical change because it is only the phase of the system is changed and it is still the substance after the process.

In a circuit, the supplied voltage is 1.5 volts, and the resistor value is 3 ohms. What is the current in the circuit?
pogonyaev
Using Ohm's Law:

V = IR

Where V = Voltage in Volts, I = Current in Ampere, R = Resistance in Ohms

V = IR

1.5 = I * 3

1.5 = 3I

3*I = 1.5

I = 1.5/3

I = 0.50 A

Current in the Circuit is 0.50 Ampere.

A 50-kg man is driving his snowmobile at a constant speed. The engine applies a force of 360 N and the coefficient of kinetic fr
S_A_V [24]

Answer:

134 kg

Explanation:

The snowmobile is moving at constant speed, so the acceleration is 0.

Sum of the forces in the x direction:

∑F = ma

F − 360 = 0

F = 360

Friction force equals the normal force times the coefficient of friction:

Nμ = 360

On level ground, the normal force equals the combined weight:

(m + 50)g μ = 360

m + 50 = 360 / (gμ)

m = -50 + 360 / (gμ)

m = -50 + 360 / (9.8 × 0.2)

m ≈ 134 kg

Round as needed.
