(25 Points) PLEASE HELP Two objects collide elastically at a relative velocity of 50 ms -1. Relative to an observer, which of these are not possible velocities for the two objects after the collision?

A. 50 ms-1 and 0 ms -1

B. 10ms-1 to the right and 60 ms-1 to the right

C. 20ms-1 to the left and 30ms-1 to the right

D. 0ms -1 and 0 ms -1

And why?

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//

the right answer is 0.3 meters per second
