The relationship between the initial velocity, final velociy, distance, and deceleration can be expressed in the following equation.

2(a)(0.270 m) = 0² - (5.70 m/s)²

The value of a (which is the deceleration) is 0.06 m/s². Thus, the answer is that the deceleration value is approximately 0.06 m/s².
