Question
Two containers of sand S and H are arranged like the blocks figure I. The containers alone have negligible mass; the sand in them has a total mass M tot; the sand in the hanging container H has mass m. You are to measure the magnitude a of the acceleration of the system in a series of experiments where m varies from experiment to experiment but M tot does not; that is, you will shift sand between the containers before each trial. 
is taken on the horizontal axis for all the plots.
The plot in figure II which gives the acceleration magnitude of the containers (taken on y-axis) as a ÷function of ratio 
is:
- 1
- 3
- 4
- 5
The correct answer is: 4

In figure shown on the right, the mass of the trolley is 100 kg, and it can move without friction on the horizontal floor. Its length is 12m. The mass of the girl is 50 kg. Friction exists between the shoes of the girl and the trolley’s upper surface, 
= 1/3. The girl can run with a maximum speed = 9 m/s on the surface of with the trolley, with respect to the surface. At t = 0 the girl starts running from rest to the right. The trolley was initially stationary.(g = 10 m/s2 )
At a certain moment when the girl was accelerating, the earth frame acceleration of the trolley is found to be 1 m/s2 . At this moment, the friction force between the girl’s shoes and the trolley’s surface is
