Answer:
So, the momentum of the boulder is zero, because its velocity is zero.
Explanation:
To calculate the momentum of the boulder, we need to use the formula:
momentum = mass x velocity
where momentum is the momentum of the object, mass is the mass of the object, and velocity is the velocity of the object.
In this case, we are given that the mass of the boulder is 3450 kg, but we are not given its velocity. Assuming that the boulder is at rest on top of the hill, its velocity is zero. Therefore, the momentum of the boulder is:
momentum = mass x velocity
momentum = 3450 kg x 0 m/s
momentum = 0 kg*m/s
So, the momentum of the boulder is zero, because its velocity is zero.
