The kinetic energy, k, of an object varies jointly with its mass, m, and the square of its velocity, v. the mass of an object staysthe same, but the velocity of the object is halved. how is the kinetic energy of the object affected?
the kinetic energy is quartered.
the kinetic energy is halved.
the kinetic energy is doubled.
the kinetic energy is quadrupled.

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

could you provide figure.

the answer is a beach is the best place to be

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
