The position of a body, moving in a plane, changes from origin to 14î + 11ĵ in 20s. What is the velocity of the body?

The position of a body, moving in a plane, changes from origin to 14î + 11ĵ in 20s. What is the velocity of the body? Correct Answer 0.7î + 0.55ĵ

The velocity of a body is the rate at which the displacement changes with time. Here, the change in position is the change in displacement, and is 14î + 11ĵ. The total time taken is 20s. Hence, the acceleration = change in displacement/time = 0.7î + 0.55ĵ.
