A jeep is moving on a straight road due north with a uniform speed of 60 km h^(-1) . When it turns left through 90°. If the speed remains unchanged after turning, the change in the velocity of the jeep in the turning process is : |

Answer» 50 KM `h^(-1)` the WEST `vec(V_(2))`=60km/h due west. `:. Deltavec(V) = vec(V_(2))-vec(V_(1))=vec(V_(2)) + (-vec(V_(1)))`…(i) `|Deltavec(V)|=sqrt(V_(2)^(2)-V_(1)^(2))=sqrt((60)^(2) + (60)^(2))` |
