Question

a biker is going at a speed of 10m/s along a straight road then uses his brakes when going about the curved path. He reduces his speed at a uniform rate from A until at C, his speed becomes 2m/s. The curvature and lengths of paths are shown in the figure.

Determine:

1. The magnitude of acceleration after he passes point B

2. The time it takes for him to travel from b to c

200 m
30 m
B

Coasting due West on your bicycle at 9.6 m/s, you encounter a sandy patch of road 6.7m across. When you leave the sandy patch your speed has been reduced by 3.8m/s to 5.8 m/s. a. Assuming the sand causes a constant acceleration, what was the bicycle’s acceleration in the sandy patch? Give both the magnitude and direction. b. How long did it take to cross the sandy patch? c. Suppose you enter the sandy patch with a speed of only 7.6 m/s. Is your final speed in this case 3.4m/s, more than 3.4m/s, or less than 3.4 m/s? Explain.
