Question

# In the figure, a block slides along a track from one level to a higher level, by moving through an intermediate valley. The track is frictionless untill the block reaches the higher level. There a frictional force stops the block in a distance d. The block's initial speed the height difference h is 1.1 m and the coefficient of kinetic friction is 0.6. The value of d is

- 1.17 m
- 1.71 m
- 7.11 m
- 11.7 m

## The correct answer is: 1.17 m

### Figure shows the roller coaster track. Each car will start from rest at point A and will roll with negligible friction. It is important that there should be at least some small positive normal force exerted by the track on the car at all points, otherwise the car would leave the track. With the above fact, the minimum safe value for the radius of curvature at point B is (g = 10 ):
