Question
A car of mass M = 800kg traveling at 40.0km/hour enters a banked turn covered with ice. The road is banked at an angle θ, and there is no friction between the road and the car's tires. (Figure 1) . Use g = 9.80m/s2 throughout this problem.
Part A
What is the radius r of the turn if θ = 20.0∘ (assuming the car continues in uniform circular motion around the turn)?

Answers
the bank angle provides the necessary centripetal force
m * v^2 / r = m * g * sin(θ) * cos(θ)
convert v to m/s, then solve for r
m * v^2 / r = m * g * sin(θ) * cos(θ)
convert v to m/s, then solve for r
