A car of mass $M=1000kg$ traveling at $65\mathrm{.}0k\frac{m}{?}$ hour enters a banked turn covered with

ice. The road is banked at an angle $,$ and there is no friction between the road and the

car's tires as shown in $($Figure $1).$ Use $g=9\mathrm{.}80\frac{m}{s^2}$ throughout this problem.

Part A

What is the radius $r$ of the turn if $=20\mathrm{.}0($assuming the car continues in uniform circular motion around the turn$)?$

Express your answer in meters.
