The mass of a truck is 6 times that of a passenger car. The speed of a car is 2 times higher than that of a truck. Compare car pulse modules?
1) The module of an impulse of any body can be calculated by the formula: P = mx * Vx.
2) Impulse of a truck: P1 = m1 * V1, of a car: P2 = m2 * V2. According to the condition: m2 = 6m1 and V2 = V1 / 2.
3) Comparison of car pulses: P2 = 6m1 * V1 / 2 = 3m1 * V1 = 3P1.
Answer: The impulse of a truck is 3 times that of a passenger car.
