A train of mass is moving on a circular track of radius with a constant speed . The length of the train is half of the perimeter of the track. Find the linear momentum of the train.
Step 1: Given parameters
Mass of train:
Length of train
Mass per unit length
Step 2: To Find:
Linear momentum of the train.
Step 3: Calculate the Linear momentum of the train.
Take a small element at an angle on the semicircle which subtends angle .
Let be the mass of this small element.
