Question

a particle moves on a track of a square field of side 6 metre and complete 3.5 round calculate its distance and displacement​

Answer 1

Answer:

In one complete cycle, it comes back to its initial position, so the displacement of the object is zero.

Distance travelled = circumference of the circle = 2πr

=2×

×3.5

=22m

Answer 2

Answer:

for one round distance=6×4=24

for 3.5 rounds distance=24×3.5= 84

displacement=length of diagonal of square= 6(2)^1/2= 6root2 = displacement
