A blue billiard ball (2kg) with initial speed 6m/s Collides with another red billiard ball (3kg) moving in the same positive x-axis. After the collision, the first ball bounces off with speed √4m/s in a direction that makes an angle +30 with the original direction. The second ball bounces in a direction that makes an angle θ2 on the other side of the first ball’s original direction. Neglect friction. Use the x-y coordinate system shown.

(a) what’s the value of θ2?

(b) determine by mathematical whether the collision was elastic or inelastic

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
