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 mov

ing 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

Answer: 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

The options that will ensure laboratory safety during the experiment will be:

• using beaker tongs to handle the hot beaker.

• checking the beaker for chips prior to heating on the hot plate.

• Turning off the hot plate after use.

We should note that the beaker tongs are simply used in the holding of the beakers that have hot liquids in them. Also, it s vital for the hot plate to be turned off after its use so as to prevent accident.
