Answer:

The acceleration of Mildred is, 1.33 m/s²  

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

A ball of mass 4.5 kg moving with speed of 2.2 m/s in the +x-direction hits a wall and bounces back with the same speed in the x
Levart [38]

Answer:

The change of the momentum of the ball is -19.8\, \frac{mkg}{s}

Explanation:

We should find \varDelta\overrightarrow{p}=\overrightarrow{p_{f}}-\overrightarrow{p_{i}} (1)with \overrightarrow{p_{i}} the initial momentum and \overrightarrow{p_{f}} the final momentum. Linear momentum is defined as \overrightarrow{p}=m\overrightarrow{v}, using that on (1):

\varDelta\overrightarrow{p}=m \overrightarrow{v_{f}}-m \overrightarrow{v_{i}} (2)

It's important to note that momentum and velocity are vectors and direction matters, so if +x direction is the direction towards the wall and the -x direction away the wall \overrightarrow{v_{i}}=+2.2\, \frac{m}{s} and \overrightarrow{v_{f}}=-2.2\, \frac{m}{s} so (2) becomes:

\varDelta\overrightarrow{p}=m(-2.2- (+2.2))=-(4.5)(4.4)

\varDelta\overrightarrow{p}=-19.8\, \frac{mkg}{s}
