An automobile, initially moving at 20 m/s, accelerates for 10 sec over a distance of 300m. What is its acceleration and average velocity? I'm confused since it says "initially moving", so I think I might need to find the final velocity in order to find the acceleration, but I don't know how. Or I could just be overthinking it

because if the tool that you are using is not balanced it there would be false mass.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

the moving of the box is a result of centripetal force. think of that  as a car or a truck in this case creates a turn, the force of friction performing upon the turned wheels of the car runs centripetal force obligatory for circular motion for the things inside it.
