The velocity vector, v, is always tangent to the path of motion.

The average speed is 12 kmh.

Solution The set up for mand kare exactly as before.

The Instantaneous Speed is.

.

at a particular instant in time.

Average velocity (V) x(t2) - x(t1) (net displacement) t2 - t1 (net time) In order to find the instantaneous velocity at an arbitrary position, we assume t1 t and t2 t t.

Instantaneous velocity The instantaneous velocity is the velocity at a specific instant of time or specific point along the path and is given by The instantaneous velocity can be positive, negative, or zero The instantaneous speed is the magnitude of the instantaneous velocity.

The instantaneous velocity of an object is the limit of the average velocity as the elapsed time approaches zero, or the derivative of x with respect to t v(t) d dtx(t).
