A toy cyclist completes one round of a square track of side 2 min 40 seconds. What will be the displacement at theend of 3 minutes? |

Answer» 52 m `= 3 min = 3 xx 60 = 180 s` Time period of revolution= 40 s `:.` Displacement in160 s `(=4xx 40) = 0 `, as toy CYCLIST will be reaching at the straight point . Thus displacement in 18 s displacement in 20 s `=sqrt((20)^2+(2)^2)=2sqrt2` m |
