Solution

When a train suddenly starts moving forward, the passenger standing in the compartment tends to fall backward is an example of inertia of rest. The reason behind this is the lower part of the passenger's body is in close contact with the train. As the train starts moving, his lower part attains the motion at once, but the upper part due to the inertia of rest cannot attain the motion simultaneously i.e. it tends to remain at the same place.
