The mass, m, of an object varies directly with its kinetic energy, k, and inversely with the square of its velocity, v. the mass of an object stays the same, but the velocity of the object is halved. how is the kinetic energy of the object affected?

a) the kinetic energy is quartered.
b) the kinetic energy is halved.
c) the kinetic energy is doubled.
d) the kinetic energy is quadrupled.

The kinetic energy is quartered!

The mass, m, of an object varies directly with its kinetic energy, K, and inversely with the square of its velocity, v. The mass of an object stays the same, but the velocity of the object is halved. How is the kinetic energy of the object affected?

The correct answer is option A) The kinetic energy is quartered.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
