Can someone help me with this problem please.
An indoor running track is square-shaped with rounded corners; each corner has a radius of 6.00 m on its inside edge. The track includes four 1.0 m wide lanes. What is the design speed on the innermost lane of the track if the banking angle is 9.0 degrees?
Thanks
(m v^2) / r = m g sinΘ
v^2 = 6.00 m * g * sin(9.0º)
