A squirrel has x-and y-coordinates (1.1 m, 3.4 m) at time t1= 0 and coordinates (5.3 m, -0.5 m) at time t2= 3.0 s. for this time interval, find (a)the components of the average velocity

Respuesta :

In position #1, at time t₁ = 0, the coordinates are (1.1 m, 3.4 m).
That is,
x₁ = 1.1 m, y₁ = 3.4 m.

In position #2, at time t₂ = 3.0 s, the coordinates are (5.3 m, -0.5 m).
That is,
x₂ = 5.3 m, y₂ = -0.5 m.

The x-component of the average velocity is
Vx = (x₂ - x₁)/(t₂ - t₁)
     = (5.3 - 1.1 m)/(3 - 0 s)
     = 1.4 m/s

Similarly, the y-component of the average velocity is
Vy = (-0.5 - 3.4)/3
     = -1.3 m/s

Answer
The x and y components of the average velocity are 1.4 m/s and -1.3 m/s respectively.
