72 In the two-dimensional collision in Fig. 9-21, the projectile particle has mass m = m, initial speed v1 = 3vo, and final speed v
= V5vo. The initially stationary target particle has mass m = 2m
and final speed vze=v2. The projectile is scattered at an angle given
by tan 6 = 2.0.(a) Find angle Oz. (b) Find vz in terms of vo- Is the
collision elastic?
be some

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!

the correct answer is "inertia"

you   need to put the sentences as we can not see them. seriously it doesn't take that long
