6. Calculate the mass of mass A in the diagram. The frame joining the masses is massless.
A
centre of mass
15 cm
30 cm
15 cm
3 kg
8 kg
40 cm
Figure 4.36​

pls can i see the diagram?

another example of kinetic energy would be,

kinetic energy   >     moving energy

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

hope that !                                         : )

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
