Answer:
1 feet
Explanation:
Frame width = x
The length of the frame will be
(bottom and top that is why x is added twice)
The width of the frame will be
Area is given by
Solving the above equation we get
Hence width of the frame is 1 ft

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>
