Explanation:
Taking west to be positive, given:
v = 17.9 m/s
a = 63.7 m/s²
t = 0.21 s
Find: v₀
v = at + v₀
17.9 m/s = (63.7 m/s²) (0.21 s) + v₀
v₀ = 4.52 m/s
The initial velocity is 4.52 m/s west.
To solve this problem, we use this formula:
s = rθ
where
s is the arc length or in this case, the distance traveled by a point of a wheel
r is the radius of the circle or the wheel
θ is the subtended angle or the angle of rotation of the wheel
Plugging in the given values and converting degrees to radians
s = 22 *128 (π/180)
s = 49.15 cm
Fallacies can be spread by companies or even people who want to sell a product for profit (money). They can also be spread on accident or on purpose by people who misunderstand the concept.
