... 20. While camping, someone forgets to strap a boat securely to the roof of a car. While taking a turn as the car left the campground, the boat comes off. The boat is most likely to ____ as it comes off the roof of the car. A. continue to follow a curved path of motion B. be pushed out C. be pulled ...

Momentum, Energy and Collisions
... For two interacting objects, if there is no net external force then we expect the total momentum of the system to be conserved. In contrast, energy is only conserved when certain types of forces are exerted between the objects. Collisions are classified as elastic (kinetic energy is conserved), inel ...

... Proof. If x ∈ S1 ⊕ S2 then by definition there exist s1 ∈ S1 , s2 ∈ S2 such that x = s1 + s2 . Assume x = s01 + s02 , s01 ∈ S1 , s02 ∈ S2 , then s1 − s01 = s2 − s02 . This implies that s1 − s01 and s2 − s02 are in S1 and also in S2 . However, S1 ∩ S2 = {0}, so we conclude s1 = s01 and s2 = s02 . We ...
