11. Momentum & Impulse

An object experiences a force given by the graph below. What value of F_max would give an impulse of 6 N⋅s?

Two collisions are represented by their force vs. time graphs. Collision A has a force that peaks at $10$ N and lasts $0.2$ s, while Collision B has a force that peaks at $7$ N and lasts $0.5$ s. Which collision has the largest impulse?

Suppose two balls, $A$ and $B$, collide on a frictionless surface. At the moment of collision, ball $B$ exerts a force on ball $A$. Which of the following arrows best represents the direction of the impulse delivered to ball $A$ by ball $B$?
