Question

A runner achieves a velocity of 11.1 m/s, 9 sec after he begins. What is his

acceleration?
Given:
Equation:
Plug in:
Answer:

Answer 1

1.23 m/s²

Step-by-step explanation:

Given:

v₀ = 0 m/s

v = 11.1 m/s

t = 9 s

Find: a

Equation:

v = at + v₀

Plug in:

11.1 m/s = a (9 s) + 0 m/s

a = 1.23 m/s²

The runner's acceleration is 1.23 m/s².
