The momentum of each cart is given by:
where
m is the mass of the cart
v is its velocity (at the bottom of the ramp)
To answer the problem, let's calculate the momentum of each of the 4 carts:
1)
2)
3)
4)
Therefore, the cart with greatest momentum is cart 3, so the right answer is
<span>- trial 3, because this trial has a large mass and a large velocity</span>

To solve this problem we will apply the concepts related to the moment of inertia and Torque, the latter both its translational and rotational expression.
According to the information given the moment of inertia of the body would be
Replacing we have
Now the translational torque would be the product between the force applied (Its own Weight) and the distance (Its center of mass at the middle)
Now the rotational torque is defined as the product between the moment of inertia and the angular acceleration, then,
Replacing,
Therefore the angular acceleration is
