Answer:
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:
[tex]p=mv[/tex]
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: [tex]p=mv=(200 kg)(6.5 m/s)=1300 kg m/s[/tex]
- cart 2: [tex]p=mv=(220 kg)(5.0 m/s)=1100 kg m/s[/tex]
- cart 3: [tex]p=mv=(240 kg)(6.4 m/s)=1536 kg m/s[/tex]
- cart 4: [tex]p=mv = (260 kg)(4.8 m/s)=1248 kg m/s[/tex]
So, we see that cart 3 is the one with largest momentum.
