Two balls, the masses of which are m and 3m, move with velocities 2U and U, respectively, in the same direction. What is the modulus of the total impulse of the system?
The formula for the total impulse of the system:
P = m * v, where m is mass, v is speed.
Since the balls move in the same direction, their impulses must be added.
Let us find the modulus of the total impulse of the system:
P = m * 2U + 3m * U = 2mU + 3mU = 5mU.
Answer: the modulus of the total impulse of the system is 5mU.
