# More PRACTICE for Unit 4-3

1) Alfonso and Sarah like to go skydiving together. Alfonso has a mass of 88 kg and Sarah has a mass of 66 kg.

While in free fall together, Alfonso pushes Sarah horizontally with a force of 12.3 N.

REMEMBER: What is the relationship of these two forces?

If their forces are equal, does this mean their accelerations are equal?

If Alfonso is the larger mass, would his acceleration be more or less than Sarah (smaller mass).

a. What is Alfonso's horizontal acceleration?

b. What is Sarah's horizontal acceleration?
