4. Object A has a mass of 0.50 kg and an initial velocity of 5.0 m/s when it collides head-on with object B of
mass 1.0 kg that is initially moving from the opposite direction at -6.0 m/s. After they collide, object A moves
away at 4.0 m/s.
A. What is the final velocity of object B?
B. Is the collision between them elastic, inelastic, or completely inelastic?

0.11 m/s and 0.28 m/s should be correct

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

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
