Kinetic energy, k, equals the product of 1 2 , the mass of an object, m, and the square of its velocity, v. write a formula for kinetic energy. then solve your formula for v.

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!

there are infinitely many solutions.
