Chapter 7: Newton’s Third Law
1. Two cars have equal masses. Car B is stopped and Car A runs into the back of Car B.
Car B exerts the same amount of force on Car A as A exerts on B.
2. All 3 50 kg blocks are at rest. Is the tension in rope 2 greater than, less than, or equal
to the tension in rope 1?
The tension is equal.
3. This pulley is set on this frictionless table. If the block is accelerating downwards, is
the tension in the string greater, less, or equal to the weight of Block B?
The tension is less than the weight of Block B.
4. A small car is pushing a l
