During a collision, an object experiences an impulse that changes its momentum. The impulse is equal to the momentum change. The impulse is the product of Force•∆Time. The momentum change is the product of Mass•∆Velocity. One can use the Force•∆Time = Mass•∆Velocity relationship to determine the set of collision parameters required to change the object's momentum from the initial state value to the final state value.
 

The diagram in this question shows a pre-collision and a post-collision momentum value. The values indicate that the momentum has changed by a certain amount. It's a negative change or loss of momentum. The amount of momentum change can be calculated by subtracting the initial value from the final value. You will need to calculate this momentum change (∆p) before you can answer the question. You should get a negative value when done correctly.
 
The momentum change is equal to the impulse. There are five impulse values provided. One of these impulse values is equal to the momentum change. Give attention to both the number and the +/- signs. You are looking for a negative impulse since the momentum change was negative.
