Blocks A (5.00 kg) and B (10.00 kg) move on a frictionless, horizontal surface. Initially, block B is at rest and block A is moving toward it at 4.00 m/s. The blocks are equipped with ideal spring bumpers. The collision is head-on, so all motion before and after the collision is along a straight line. What is the maximum energy stored in the spring bumpers during the collision process

1.33m/s: 13.326j

Explanation:

M1U1+M2U2=V(M1+M2)

M1=5kg, M2=10kg

U1=4.00m/s, U2=0

5*4+10*0=V(10+5)

20+0=15V

20=15V

V=20/15

V=1.333m/s

K. E=1/2MV^2

K. E= 1/2*15*1.332^2

K. E= 1/2*15*1.77689

K. E=26.65335/2

K. E=13.326j

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).
