Question $10$: A runner passes a check point moving at $4\frac{m}{s}.$ They keep that same speed for $2$ seconds and then stop and rest for $1$ second. If the check point is at $x=0m$ and $t=0s$ then:

a$.$ What is their position at $t=3s?$

b$.$ Sketch a graph of their motion on the axis below.

Question $11$: A baseball player tries sliding into home base which is $2\mathrm{.}84$ m away from him. If he's moving at $9\mathrm{.}36\frac{m}{s}$ and plans to come to a stop exactly at the base, what acceleration will he need?

an arow at a $,cos(2\mathrm{.}844)=0,998sin(2\mathrm{.}84)=0\mathrm{.}0495$

$\frac{0\mathrm{.}998}{0\mathrm{.}0495}=20\mathrm{.}1616$

$\frac{0\mathrm{.}998(2\mathrm{.}84{)}^{12}}{2(0\mathrm{.}998{)}^2(2\mathrm{.}840\mathrm{.}495)}$

$=63482$
