 Homework Statement:

The arrival of a hurricane is predicted with wind speeds of 120 mph (miles per hour). The force exerted by a 60 mph gale on the sides of a train locomotive has been measured and found to be F. Will the hurricane forces on the same locomotive be:
1. The same as F
2. Twice as large as F
3. Three times as large as F
4. Four times as large as F
 Relevant Equations:
 F=Δp/Δt and Δp = Δ(mv)
The marker wrote that the answer is 4 and it's because m and v double. I don't understand how m doubles??
