Students are completing a lab in which they let a lab cart roll down a ramp. the students record the mass of the cart, the height of the ramp, and the velocity at the bottom of the ramp. the students then calculate the momentum of the cart at the bottom of the ramp. which trial’s cart has the greatest momentum at the bottom of the ramp? trial 1, because this trial has the greatest velocitytrial 2, because this trial has the greatest ramp heighttrial 3, because this trial has a large mass and a large velocitytrial 4, because this trial has the greatest mass

trial 3, because this trial has a large mass and a large velocity

Explanation:

The momentum of each cart at the bottom of the ramp can be calculated as follows:

where

m is the mass of the cart

v is the velocity of the cart at the bottom of the ramp

Let's use this formula to calculate the momentum of each cart:

- cart 1:

- cart 2:

- cart 3:

- cart 4:

So, we see that cart 3 is the one with largest momentum.

the second one and the forth one are in the purple because they are opinions and the rest are in the yellow

explanation:

it becomes positively charged by charging it
