You go to an amusement park with your friend betty, who wants to ride the 70-m-diameter ferris wheel. she starts the ride at the lowest point of a wheel that, as you face it, rotates counterclockwise.
part awhat is the magnitude of her displacement vector when the wheel has rotated by an angle of 40 ∘? express your answer with the appropriate units. part bwhat is the direction of her displacement vector when the wheel has rotated by an angle of 40 ∘, measured counterclockwise from the horizontal?

Part a)

Part b)

Explanation:

Part a)

As we know that initially the position vector is r

then the same magnitude position vector is rotated by 40 degree angle

so displacement magnitude is the magnitude of change in position vector

so it is given as

Part b)

now we need to find the direction of the displacement vector

so let say it makes an angle with x axis so we have

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
