Final answer:
The speed of a 0.25 kg arrow with a momentum of 8 kg·m/s is 32 m/s, which is found by dividing the momentum by the mass.
Step-by-step explanation:
The speed of a 0.25 kg arrow with a momentum of 8 kg·m/s can be found using the formula for momentum, which is momentum = mass × velocity. To find the velocity, we simply divide the momentum by the mass. Therefore:
velocity = momentum / mass
velocity = 8 kg·m/s / 0.25 kg
velocity = 32 m/s
So, the correct answer is A) 32 m/s.
