Answer:
The skater 1 and skater 2 have a final speed of 2.02m/s and 2.63m/s respectively.
Explanation:
To solve the problem it is necessary to go back to the theory of conservation of momentum, specifically in relation to the collision of bodies. In this case both have different addresses, consideration that will be understood later.
By definition it is known that the conservation of the moment is given by:
Our values are given by,
As the skater 1 run in x direction, there is not component in Y direction. Then,
Skate 1:
Skate 2:
Then, if we applying the formula in X direction:
m_1v_{x1}+m_2v_{x2}=(m_1+m_2)v_{fx}
75*5.45-75*1.41=(75+75)v_{fx}
Re-arrange and solving for v_{fx}
v_{fx}=\frac{4.04}{2}
v_{fx}=2.02m/s
Now applying the formula in Y direction:
Therefore the skater 1 and skater 2 have a final speed of 2.02m/s and 2.63m/s respectively.
Answer:
To Calculate Molecular Mass of O3
you should know Atomic mass of O
Atomic mass of oxygen(O) = 16
As O3 consist 3 atoms ,
So, Molecular mass of O3 =>3× 16
=> 48 g/mol
=> 0.048 kg/mol
Explanation:
As a tornado or other storm system passes over a building, low pressure can tug a roof upward. When those forces surpass the force exerted by the weight of the roof, the structure flies up and is swept away by wind currents..
The final velocity of the cart at the given mass is 4.36 m/s.
The given parameters;
- <em>mass of the cart, m = 1 kg</em>
- <em>work done on the cart, W = 5 J</em>
- <em>initial velocity of the cart, u = 3 m/s</em>
The distance traveled by the cart is calculated as follows;
Fd = W
mgh = W
The final velocity of the cart is calculated as follows;
Thus, the final velocity of the cart at the given mass is 4.36 m/s.
