To move a loaded trolley, we have to **apply a force** to it. This can be done in two ways: by **pushing** or **pulling** the trolley.
### Step-by-Step Solution:
1. **Understanding the Trolley**: A loaded trolley is a cart that carries weight. To move it, we need to overcome the resistance due to the weight and friction.
2. **Applying Force**: To initiate movement, we need to apply a force. This force can be exerted in two different ways:
- **Pulling the Trolley**: By pulling the trolley towards us, we apply a force that helps to lift some of the weight off the wheels, reducing friction and making it easier to move.

If a person moves a trolley for a distance of 10 m with a force of 50 , then the work done is:
A trolley was moving horizontally on a smooth ground with velocity v with respect to the earth. Suddenly a man starts running from rear end of the trolley with a velocity (3//2)v with respect to the trolley. After reaching the other end, the man turns back and continues running with a velocity (3//2)v with respect to trolley in opposite direction. If the length of the trolley is L, find the displacement of the man with respect to earth when he reaches the starting point on the trolley. Mass of the trolley is equal to the mass of the man.
A child is sitting at one end of a long trolley moving with a uniform speed v on a smooth horizontal track. If the child starts running towards the other end of the trolley with a speed u (w.r.t. trolley), the speed of the centre of mass of the system will.
Assertion:- A coin dropped in a closed trolley moving-down the smooth inclined plane. appears to fall normal to the floor of the trolley to a man fixed with the trolley. Reason:- The acceleration of coin relative to car (i.e. man) is g cos theta downward perpendicular inclined plane.
In the figure shown, the mass of the trolley is 100 kg and it can move without friction on the horizontal floor. It length is 12 cm. The mass of the girl is 50 kg. Friction exists between is 12 m. The mass of the girl is 50 kg. Friction exists between the shoes of the girl and the trolley's upper surface, with mu = 1//3 , The girl can run with a maximum speed = 9 m//s on the surface of the trolley, with respect to the surface = 9 m//s on the surface of thr trolley, with respect to the surface. At t=0 the girlm starts running from left to the right. The trolley was initially stationary. (g = 10 m//s^(2)) The displacement of the trolley by the time the girl reaches the right end of the trolley is :
