Point B represents a distance half-way down the ramp. If the ball rolls down the ramp, how much potential energy has been converted to kinetic energy at point B?

A) 0 J

B) 25 J

C) 50 J

D) 100 J

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!
