Consider an elastic collision between two particles with unequal masses (m m2) where the second particle is initially at rest. Show that the angle between the two outgoing velocities satisfies θ < π/2 if m1 > m2, but θ >π/2 if m1 < m2.

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.
