Question

in figure shown, mass of the trolley is 100 kg, it can move without friction on the horizontal floor. Its length is 12m. The mass of the girl is 50 kg. Friction exists between shoes of the girl and trolley;s upper surface, with mu = 1/3. the girl can run with a max speed of 9m/s on the surface of the trolley, with respect to the surface. At t=0, the girl starts running from rest to right. The trolley was initially at rest. at certain moment when the girl was accelerating, the earth frame acceleration of the trolley is found to be 1m/s^2. At the is moment, the friction force between the girl's shoes and the trolley surface
