Question $5(5$ points$)$

A car drives around a circular track of diameter $57m$ at a constant speed of $35\mathrm{.}3\frac{m}{s}.$ During the time it takes the car to travel $135$ degrees around, what is the magnitude of the car $s$ average acceleration?

$43\mathrm{.}72\frac{m}{s^{{?}^{{?}^{?}}}}2$

$21\mathrm{.}86\frac{m}{s^{{?}^{{?}^{?}}}}2$

$34\mathrm{.}29\frac{m}{s^{{?}^{{?}^{?}}}}2$

$0\frac{m}{s^{{?}^{{?}^{?}}}}2$

Question $6(5$ points$)$

You launch a projectile with an initial speed of $45\mathrm{.}6\frac{m}{s}$ from the top of a building $42\mathrm{.}4m$ above the ground, at an angle of $51\mathrm{.}7$ degrees above the horizontal. How far from the base of the building does the projectile land on the ground?

$2006\mathrm{.}2m$

$220\mathrm{.}9m$

$294\mathrm{.}4m$

$235\mathrm{.}5m$
