Question

Pluto was laying at rest in the sun and notices the smell of meat. He runs at 8 m/s to the smell of the meat. How fast is the dog accelerating in 2 s ?

Answer 1

Given parameters:

Initial velocity(body is at rest) = 0m/s

Final velocity = 8m/s

Time of acceleration  = 2s

Unknown:

Acceleration of the dog = ?

Acceleration is defined as the change in velocity with time.

Mathematically;

              Acceleration  = $\frac{Final velocity - Initial velocity}{time taken}$

         Now input the given parameters and solve;

         Acceleration  = $\frac{8-0}{2}$

         Acceleration  = 4m/s²

The dog is accelerating at a rate of 4m/s²
