A soccer player carries the ball for a distance of 40.0 m in the direction 42.0° west of south. find the westward component of t
he ball's displacement.
1 answer:
Actually what the problem meant about the westward component of the ball’s displacement is the horizontal component of the displacement. To help us better understand the problem, I attached a figure of the situation.
We can see from the figure that to solve for the value of the horizontal component, we have to make use of the sin function. That is:
sin θ = side opposite to the angle / hypotenuse of the triangle
sin 42 = x / 40 m
x = (40 m) sin 42
x = 26.77 m
Therefore the ball has a westward displacement of about 26.77 m

Answer:
The wavelength in miles is <u>0.1165 miles</u>.
Explanation:
Given:
Wavelength of the radio wave is 187.37 m.
Now, the wavelength is given in meters.
We need to convert the wavelength from meters to miles.
In order to convert meters to miles, we have to use their conversion factor.
We know that,
1 meter =
Therefore, the conversion factor is given as:
So, the wavelength in miles is given as:
Hence, the wavelength in miles is 0.1165 miles.
