Final answer:
The magnitude of the momentum change the object experiences, due to the resistive force over a duration of 0.30 seconds, is 6 N·s or 6 kg·m/s.
Step-by-step explanation:
The student's question about the momentum change experienced by the object involves applying the concept of impulse in Physics. Impulse is the product of force and time, which equals the change in momentum.
To calculate the momentum change caused by a resistive force acting over a certain time, we use the formula: Impulse (J) = Force (F) × Time (t). Here, the resistive force is 20 newtons, and the time is 0.30 seconds.
Impulse (J) = 20 N × 0.30 s = 6 N·s
Since impulse is equivalent to the change in momentum (Δp), the magnitude of momentum change the object experiences is 6 N·s or 6 kg·m/s.
The momentum change (magnitude only) experienced by an object can be calculated using the formula:
Momentum change = Force * Time
Plugging in the given values, we have:
Momentum change = 20 N * 0.30 s = 6 N/s
Therefore, the magnitude of the momentum change experienced by the object is approximately 6 N/s.
