Answer:
A, C and D
Explanation:
The impulse is defined as the product between the force (F) and the time of the collision (t):
[tex]I=Ft[/tex]
Let's apply the formula to calculate the impulse for each situation:
A) [tex]I=Ft=(20)(\frac{1}{2})=10[/tex]
B) [tex]I=Ft=(3)(4)=12[/tex]
C) [tex]I=Ft=(5)(2)=10[/tex]
D) [tex]I=Ft=(10)(1)=10[/tex]
We see that the situations in which the impulse is equal to 10 units are:
A, C and D
