Question:

3. A car of mass m = 1300 kg traveling at 55.0 km/hour enters a banked turn covered with ice. The road is banked at an angle 0,

3. A car of mass m = 1300 kg
traveling at 55.0 km/hour enters
a banked turn covered with ice.
The road is banked at an angle 0,
and there is no friction between
the road and the car's tires. Use
g= -9.80 m/s2 throughout this
problem. What is the radius r of
the turn if 0 = 20.0° (assuming
the car continues in uniform
circular motion around the turn)?
