itially at rest, makes a break for the goal. When she starts to move, you pass A so that it moves with constant velocity to reach her 3 seconds later and she sco game, you start to wonder how fast you passed the puck to reach her at the ri score. You estimate her acceleration was a = 1.5 m/s² at an angle of 0A = 70° w to the x-axis, and her initial position is FAO = (-10, 0, -2) (m). rdinate system is shown below from the viewpoint of looking down on the rink.

Given Data

• The acceleration of the alice is:$a=1.5 \mathrm{m}/\mathrm{s}$
• The angle is:${\theta }_A=70°$
• The initial position of the alice is:${\overrightarrow{r}}_{AO}=\left\{-10,0,-2\right\}\mathrm{m}$

To solve the D and E part, here we need to soolve all sub parts because they are interlinked with each other. So we solve all parts.

Nwo the x and z component of the acceleration is consider as,

$\begin{array}{rcl}{a}_x& =& a\cos {\theta }_A\\ a_x& =& 1.5\cos 70\\ a_x& =& 0.513 \mathrm{m}/{\mathrm{s}}^2\end{array}$

Nwo the z component of the acceleration is consider as,

$\begin{array}{rcl}{a}_z& =& a\sin {\theta }_A\\ a_z& =& 1.5\sin 70\\ a_z& =& 1.4095 \mathrm{m}/{\mathrm{s}}^2\\ {\mathrm{a}}_{\mathrm{z}}& \cong & 1.41 \mathrm{m}/{\mathrm{s}}^2\end{array}$
