Aparticle travels in a straight line with speed v. the particle slows down and changes direction. the new speed of the particle is v\2 the new velocity has a component of v\4 in the same direction as the initial path of the particle. through which angle has the particle turned? a 27° b 30° c 45° d 60°

D 60°

Explanation:

Using trigonometry:

- The new speed (v/2) of the particle corresponds to the hypothenuse

- The component of v/4 represents the side adjacent  to the angle that we want fo find,

So we can write:

So we find the angle

a.) is the correct answer.
