120/60= 2m per s
220/55= 4m per s
720/80= 9m per s
Fastest run: 3rd run
Speed: 9m per s
Slowest: 1st run
Speed: 2m per s
We will use formula for the orbital velocity of Venus, which is v = 35.02 km/s.
An average distance to the Sun ( In kilometers ) is:
R = 0.723 * 149,579,871 km= 108,150,260 km.
Than we will calculate the orbital period ( T ).
v = 2 π R / T
T = 2 π R / v
T = 2 * 3.14 * 108,150,260 km / 126,072 km/s
T = 5389.75 s ≈ <span>224.5 days
The orbital period of Venus is approximately 224.5 days.</span>
Answer:
Correct answer: Ek = I² / 2 · m
Explanation:
The formula by which kinetic energy is calculated is:
Ek = m V² / 2
The formula by which momentum i prefer the name impulse is calculated is:
I = m V
We will transform the formula for kinetic energy on the next way:
Ek = m V² / 2 we will multiply numerator and denominator with m and get:
Ek = m² V² / 2 m = (m v)² / 2 m = I² / 2 m
Ek = I² / 2 m
God is with you!!!
