Irequire on this physics question, i made an attempt at answering but i just have no idea.

It traveled 24 centimeters

Explanation:

The displacement of the object is equal to the area under the velocity vs time graph.

We can split this graph into two shapes, a triangle and a rectangle.  So the total area is:

A = ½bh + wh

A = ½ (4 s − 0 s) (4 cm/s) + (8 s − 4 s) (4 cm/s)

A = 8 cm + 16 cm

A = 24 cm

another example of kinetic energy would be,

kinetic energy   >     moving energy

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

hope that !                                         : )

in physics zero. in muscle fatigue could be high
