Answer 1

The acceleration of Mildred is, 1.33 m/s²

Step-by-step explanation:

Given data,

The initial velocity of Mildred, u = 12 m/s

The final velocity of Mildred, v = 8 m/s

The time period of travel, t = 3 s

The acceleration of Mildred,

a = (v-u)/t

a = (8 - 12) /3

= -4/3

= -1.33 m/s²

The negative sign indicates that the Mildred is decelerating.

Hence, the acceleration of Mildred is, 1.33 m/s²
