Acar battery seems to be malfunctioning (not providing the proper voltage and current to start your car). while the car is off and you are not trying to start it, a friend uses a voltmeter to measure the voltage and finds that your battery voltage is 12.0 v, just as it is supposed to be. after the voltage check, you try to start your car again to no avail. can you rule out the battery as the problem?

No. You cannot rule out the battery even after the open circuit voltage measurement. The open-circuit voltage may not have changed but the battery's internal resistance may have greatly increased.

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
