A cyclist goes around a circular track of circumference 410 m in 20 s.

1.	A cyclist goes around a circular track of circumference 410 m in 20 s. Find the angle that his cycle makes with the vertical.
Answer» Solution :`R = 410//2pi = 65.29 m, t = 20 s, V= 410//20 = 20.5 m//s, tan theta = v^(2)//RG = 0.6568, theta = 33.3^(@)`
