cyclist is going around a curve at constant speed, is he accelerating? "so, what is the direction of his acceleration, and how the direction is related to velocity? Explain using a graph for full credit. A Sine Law Straight-Line Motion ant Acceleration a a / sin a = b / sin B = c/ s C Cosine Law b al = b' + c' - zbc cos a B b' = a + c' - zac cos B B c' = a + b'- Zab cosy
