Question

A body moves on three quarters of circle of radius r. find the value of the displacement and the distance travelled by the body​

Answer 1

Answer:

Displacement is sqrt2 * r and distance is 3/2*pi*r

Explanation:

Distance is length of path travelled so it 3/4 parts of the circumference while displacement is the shortest length between starting and ending points which here we can find through pythagoras theorem as x^2 = r^2 + r^2.
