Ms. Hurlbutt's dog, Bear, was casually trotting through a field at a velocity of 5 m/s. Suddenly, he sees a squirrel. He takes off into a sprint and reaches a velocity of 15 m/s in 2 seconds. What is his acceleration?

• 5 m/s2

• 10 m/s2

• 15 m/s2

• 1 m/s2

what is the definition of acceleration?

• distance divided by time

• The change in distance in a period of time in a specific direction

• The change in distance in a period of time

• The change in velocity in a period of time

What is the equation for speed?

• speed = distance x time

• speed = time / distance

• speed = distance / time
