What is the modulus of the velocity of a body with mass m = 4.0, if the modulus of its impulse is p = 60 kg • m / s?
| March 10, 2021 | education
The momentum of a body is equal to the product of the body’s mass by its velocity.
Р = m * V, where Р – body impulse (Р = 60 kg * m / s), m – body weight (m = 4 kg), V – body speed (m / s).
Let’s express and calculate the speed of the body:
V = P / m = 60/4 = 15 m / s.
Answer: The speed of the body is 15 m / s.
