7. A rope is strong enough to withstand a 750 N force<br />
without breaking. If two people pull on opposite<br />
ends <strong>of</strong> the rope, each with a force <strong>of</strong> 500 N, will it<br />
break? Explain.<br />
8. State Newton’s third law <strong>of</strong> motion. Describe an<br />
example <strong>of</strong> a situation involving the law <strong>of</strong> action<br />
and reaction that you have not already used.<br />
9. Two tug-<strong>of</strong>-war teams are at opposite ends <strong>of</strong> a<br />
rope. Newton’s third law says that the force exerted<br />
by team A will equal the force that team B exerts on<br />
team A. How can either team win the tug-<strong>of</strong>-war?<br />
10. (a) Define momentum.<br />
(b) Why is momentum considered a very important<br />
quantity in physics?<br />
<strong>11</strong>. (a) Define impulse.<br />
(b) What is the impulse due to a force that causes<br />
the velocity <strong>of</strong> a 46 g golf ball to change from<br />
0 m/s to 60.0 m/s in 0.50 ms?<br />
(c) What force was applied to the ball?<br />
