Final answer:
The force on a vehicle experiencing a change in momentum of +358 kg·m/s over 5.51 seconds is calculated using Newton's second law of motion and is approximately 64.974 Newtons (N).
Step-by-step explanation:
To calculate the force on a vehicle given a change in momentum and the time span, we can apply Newton's second law of motion, where force equals the change in momentum (mass times change in velocity) divided by the time over which the change occurs (F=Δp/t).
In this case, the change in momentum (Δp) is +358 kg·m/s, and the time (Δt) is 5.51 seconds. Using the formula for force, we get:
F = Δp / Δt
F = 358 kg·m/s / 5.51 s
F = 64.974 kg·m/s² or N (rounded to three decimal places)
Therefore, the force on the vehicle during this time is approximately 64.974 Newtons (N).
