Question

April moves from a position that is 5 m north of her front door to a new position that is 3 m south of her front door. If this movement takes her 4 seconds what is her velocity?

Answer 1

Velocity =

(displacement)/(time for the displacement), in the direction of the displacement.

Displacement = 8 m south
Time for the displacement = 4 seconds
Direction of the displacement = south

Velocity (8 m south) / (4 seconds), to the south

Velocity = 2 m/s, toward the south
