Answer:
2m/s²
Explanation:
The initial acceleration of the wagon can be determined from;
Force = mass x acceleration
mass = 50kg
Initial force applied = 100N
Now;
100 = 50 x a
a = 2m/s²
So;
When a force of 200N applied;
200 = 50 x a
a = 4m/s²
Therefore, the wagon will quickly accelerate by 4 - 2 = 2m/s²
