Andrei takes his new gravel bike out in his village. He is going at a speed of 15 m/s along a straight road when he applies the brakes to slow down at a curved section. He REDUCES his speed at a uniform rate from point A until his speed at C becomes 5 m/s. The curved section B-C has a constant curvature of 200 m and a length of 60 m

Andrei takes his new gravel bike out in his village. He is going at a speed of 15 m/s along a straight road when he applies the brakes to slow down at a curved
section. He REDUCES his speed at a uniform rate from point A until his speed at C becomes 5 m/s. The curved section B-C has a constant curvature of 200 m
and a length of 60 m.
200 m
30 m
60 m
1. Which of the following statements is FALSE regarding the motion
Andrei along the curved portion of the path, B-C?
His velocity is tangent to the path.
His normal acceleration is directed towards the center of curvature of the path. n of Andrei just after he passes point B?
His acceleration is tangent to the path.
