From the question we are told that
The speed of the bicycle is ![v_b = 22\ mph = 22 * \frac{5280}{3600} = 32.26 ft/s](https://tex.z-dn.net/?f=v_b%20%3D%2022%5C%20mph%20%3D%2022%20%2A%20%5Cfrac%7B5280%7D%7B3600%7D%20%20%20%3D%20%2032.26%20ft%2Fs)
The distance between the axial is ![d = 42 \ in](https://tex.z-dn.net/?f=d%20%3D%2042%20%5C%20in)
The mass center of the cyclist and the bicycle is
behind the front axle
The mass center of the cyclist and the bicycle is
above the ground
For the bicycle not to be thrown over the
Momentum about the back wheel must be zero so
![\sum _B = 0](https://tex.z-dn.net/?f=%5Csum%20_B%20%3D%200)
=> ![mg (26) = ma(40)](https://tex.z-dn.net/?f=mg%20%2826%29%20%3D%20ma%2840%29)
=> ![a = \frac{26}{40} g](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7B26%7D%7B40%7D%20g)
Here ![g = 32.2 ft/s^2](https://tex.z-dn.net/?f=g%20%3D%2032.2%20ft%2Fs%5E2)
So ![a = \frac{26}{40} (32.2)](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7B26%7D%7B40%7D%20%2832.2%29)
Apply the equation of motion to this motion we have
![v^2 = u^2 + 2as](https://tex.z-dn.net/?f=v%5E2%20%3D%20u%5E2%20%2B%202as)
Where ![u = 32.26 ft /s](https://tex.z-dn.net/?f=u%20%3D%2032.26%20ft%20%2Fs)
and
since the bicycle is coming to a stop
![v^2 = (32.26)^2 - 2(20.93) S](https://tex.z-dn.net/?f=v%5E2%20%3D%20%2832.26%29%5E2%20-%202%2820.93%29%20S)

No because you don’t learn about synthetic inventions yet in your first year
Explanation:
The Simple Pendulum. A simple pendulum is defined to have a point mass, also known as the pendulum bob, which is suspended from a string of length L with negligible mass ((Figure)). Here, the only forces acting on the bob are the force of gravity (i.e., the weight of the bob) and tension from the string.

Answer:
To balance an equation such as Mg + O2 → MgO, the number of the atoms in the product must equal the number of the atoms in the reactant. Mg + O2 --> MgO. To balance an equation, we CAN change coefficients, but NOT SUBSCRIPTS to balance equations.
