You're out for run. Your initial velocity is 1.5 m/s. Suddenly a crazy dog starts chasing you and you accelerate to a velocity of 3 m/s. It takes you 10 seconds to find a safe place to hide from the Chihuahua. What was your displacement?

The displacement of your motion during the entire motion is 22.5 m

The given parameters;

  • your initial velocity, u = 1.5 m/s
  • your final velocity , v = 3 m/s
  • time of motion, t = 10 s

The displacement of your motion during the entire motion is calculated from your average velocity and time of motion.

This magnitude of this displacement is calculated  as follows;

[tex]s = (\frac{u+ v}{2} )t\\\\s = (\frac{1.5 + 3}{2} ) \times 10\\\\s = 22.5 \ m[/tex]

Thus, the displacement of your motion during the entire motion is 22.5 m.
