Explanation:
From the question we are told that
The mass of the coal car is
The velocity is
The load of coal dropped is
Generally the momentum of the system before the coal is added is mathematically represented as
=>
=>
Generally from the law of momentum conservation is mathematically represented as
Here is the velocity of the load before it is dropped and the value is 0 m/s
So
=>
=>
When v = 1m/s and remain the same
Then
=>
=>
=>
<u>We are given:</u>
2 Vectors A and B
A = î - 5j
B = 2î - 10j
<u>Proving that the given vectors are Parallel:</u>
We can rewrite the Vector B as: B = 2(î - 5j)
Since A = î - 5j
Vector B can be written as:
B = 2(A vector)
this means that the magnitude of Vector B is twice of vector A but their direction is the same
Since the 2 vectors are moving in the same direction, they are parallel
Answer:
Explanation:
When the suitcase is being released, it has a horizontal velocity of v0, a vertical velocity of 0 and vertical acceleration of g
The time it takes for it to drop by the vertical distance of α under acceleration g can be solved using the following equation of motion
This is also the time it takes for the suitcase to travel horizontally at the rate of v0. So the horizontal distance it travels is
Answer: one brain... humans have one brain
Explanation: humans have many parts of the brain but they only have one brain there are left brain right brain people. Right brain tends to me more creative and left brain is more logical but its is all still the same brain you just use different parts of the brain at one time
