Question

Problem 3: An object moves from point A to B to C to D and finally to A along the circle shown in the
figure below
a) Find the distance covered by the moving object.
b) Find the magnitude and direction of the displacement of the object
1 km​

Answer 1

Answer:

Distance = Length of path travelled

=AB+BC

=15+9

=24km

Displacement = Shortest path from initial to final position

=AC

=

(AB)

2

+(BC)

2

{Pythagoras Theorem}

=

225+81

=17.5km

solution

Answer 2

Answer:

a) the distance is

circumference= 2*π*radius

b) the magnitude of displacement is 0

direction I think it is nothing as the object is back at its place
