Answer:
It will be doubled
Step-by-step explanation:
F = ma
Let's consider m = 1 (the mass of the cart is not changing so it is constant),
F = 2, and a = 4.
2 = 1 x 4
When doubling force we need to maintain equality so acceleration should double too. To understand it better find the ratio of force and acceleration 2/4 = 1/2. The ratio of force to acceleration should always equal half in all scenarios, this way we can see how equality is maintained.
2x2 = 1 x (4x2)
4 = 1 x 8, and the ratio of force to acceleration is 4/8 = 1/2.
