Determine the impulse of a washer with a mass of 150 g flying at a speed of 40 m / s.
September 30, 2021
The momentum of the washer will be equal to the product of the mass of the washer by its speed.
P = m * V, where P is the momentum of the washer (kg * m / s), m is the mass of the washer (m = 150 g = 0.15 kg), V is the speed of the washer (V = 40 m / s).
Let’s calculate the puck momentum:
P = m * V = 0.15 * 40 = 6 kg * m / s.
Answer: The momentum of the washer is 6 kg * m / s.
