Question 4 :)

The smaller mass m1 is 100 grams while the larger mass m2 is 500 grams. This means that m2=5*m1. We can use this fact to place it in the equation that you found earlier to find the final speed Vf in terms of the initial speed Vi.

Looks good! Now you can reduce the equation by using the fact that m2 is equal to 5*m1.
