Question

write the difference between distance travelled by a body and it's displacement an ant travels distance of 12 cm from ato b and then moves a distance of 9 cm at right angle to ab find the resultant displacement and the total distance covered by it

Answer 1

Hey,

Total distance travelled by ant=12+9=21 cm
Total displacement=√12²+9²
                              =√225
                              =15 cm 

HOPE IT HELPS YOU:-))

Answer 2

${9}^{2} + {12}^{2} = {15}^{2}$
