The vehicle speed is 20 m / s, and its impulse is 3 · 10 ^ 4 kg · m / s. What is the mass of a car?

To calculate the mass of the car, we use the formula: P = m * V, from where we express: m = P / m.
Values of variables: P – impulse of a given vehicle (P = 3 * 10 ^ 4 kg * m / s); V – speed of movement (V = 20 m / s).
Let’s perform the calculation: m = P / m = 3 * 10 ^ 4/20 = 1.5 * 10 ^ 3 kg = 1.5 tons.
Answer: The mass of the car is 1.5 tons.
