Question

You accelerate from 2m/s to 6m/s while traveling a distance of 2m; what was your acceleration?

A.4 m/s^2
B.8 m/s^2
C.12 m/s^2
D.16 m/s^2

Answer 1

The acceleration is 8 m/s²

Step-by-step explanation:

The given parameters are;

The initial velocity, u = 2 m/s

The final velocity, v = 6 m/s

The distance the acceleration took place, s = 2 m

The acceleration, a, can be found from the following kinematic equation;

v² = u² + 2·a·s

By substituting the values, we have;

6² = 2² + 2 × a × 2

6² - 2² = 2 × a × 2

32 = 4·a

a = 32/4 = 8 m/s²

The acceleration, a, of the given motion = 8 m/s².
