Question

Rajesh moving in a square field of side 10 M and he cover boundary of field in 40 second what will be its displacement after 3 minutes 40 seconds

Answer 1

Displacement is zero... because his starting point and ending point is the same...

Answer 2

Solution

Given speed= 10m/40sec= 1/4 m/s

distance travelled in 3 minutes 40 seconds or

(60*3)+40= 180+40= 220 sec.

so,distance travelled= speed*time

= 1/4*220= 44M

Now,displacement= 4m
