Answer:
to absorb extra light- E.
KE= 1/2MV^2 - equation
KE= 1/2 (2 kg)(15 m/s)^2 - plug it to the equation
KE= (1 kg)(225 m/s) - multiply
KE= 225 J - Answer (letter D)
Hope this helps
Answer:
O 47 kg. m/s if they were initially headed opposite direction
O 145 kg. m/s if they were initially headed the same direction
The other two are possibilities as well if velocities are initially at an angle
