A railroad car containing an angry bull is standing onthe

nata0808 [166]

Answer:

$v_{f}$ = - M / m v

Explanation:

We must define a system formed by the wagon and the torro, in this case the forces of the movement are internal, so the moment is preserved, write the moment in two moments

Initial. Before the bull's movement, in this case the two are still

p₀ = 0

Final. The bull is moving

$p_{f}$ = M v + m $v_{f}$

p₀ = $p_{f}$

0 = M v + m $v_{f}$

We cleared the train speed

$v_{f}$ = - M / m v

The negative sign indicates that the train moves in the opposite direction of the bull

The reason that oscillating systems are good to use for clocks is:

Neporo4naja [7]

Answer:

A. The period of an oscillation does not depend upon amplitude.

Explanation:

The period of a spring-mass system is:

T = 1/f = 2π√(m/k)

where f is the frequency, m is the mass, and k is the spring constant.

The answer isn't B. There are no frictionless systems in the real world.

The answer isn't C or D. As shown, the frequency is a function of both the mass and the spring constant.

The answer isn't E. Turning motion into heat is not an advantage for a clock.

The correct answer is A. The period of the system does not depend on the amplitude.

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.

"A hiker starts at point P and walks 2.0 kilometers due east and then 1.4 kilometers due north. The vectors in the diagram below

Law Incorporation [45]

Here, you need to use your "Protractor" as it is given in the question, but we can calculate the value with the help of our mathematical calculation too:
[ Protractor can be use only in real life, not here ]

Draw an imaginary line from initial position to final position.
Now, In that triangle, tan x = P/B
tan x = 1.4 / 2
tan x = 0.70
x = tan⁻¹ (0.70)
x = 35 [ tan 35 = 0.70 ]

In short, Your Answer would be 35 degrees

Hope this helps!
