The average velocity is a vector magnitude we can find that its value is:
v = 3.63 10-2 m/ s
with a direction 74 to the South of the East
Giving parameters
- The tabulated displacements
- The time of the motion t = 300 s
To find
The velocity in a vector quantity that is defined as the change in displacement between time during the interval
v =
Where v is the veloicity, Δs and Δt are de positivo and time variation
To find the displacement let's use the Pythagoras' theorem
d =
We assume that the displacements to the right (east) and upwards (north) are positive
Δx = 17-14
Δx = 3 m
Δy = 12 -22.5
Δy = -10.5 m
The distance traveled is
d =
d = 10.9 m
The speed module is
v = 10.9 / 300
v = 3.63 10⁻² m / s
The direction of this velocity is given by the angle of this displacement can be found using trigonometry
tan θ =
θ = tan⁻¹
θ = tan⁻¹
θ = -74º
This angle is measured clockwise from the positive side of the x-axis.
Orea way to give this angle is
θ = 74 south of East
In conclusion the average speed is
v = 3.63 10-2 m / s
With a direction 74 to the South of the East
