Answer the following questions Remember:
position is equal to the velocity multiplied by time plus the initial position (x = v*t + xi)
velocity is equal to the displacement divided by time
(v = x/t)

1) A person riding their bike on a nice cloudy day travels 50 meters in 20 seconds. How fast are they moving?

2) A car going down the road has a velocity of 20 m/s. If the car continues at this rate for 7 seconds how far did the car go?

3) A professional baseball player can throw the ball around 45 m/s if the distance between the pitcher and the batter is 18.39 m. How much time does it take for the ball to get to the batter?

4) The average NASCAR drive is moving at around 100 m/s. If the NASCAR track is roughly 850 m. How long does it take the NASCAR drivers to make a lap?

Did the proton move into a region of higher potential or lower potential? did the proton move into a region of higher potential or lower potential? because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.request answerpart bwhat was the potential difference that stopped the proton? express your answer with the appropriate units.î”v î” v = nothingnothingrequest answerpart cwhat was the initial kinetic energy of the proton, in electron volts? express your answer in electron volts.ki k i = nothing ev request answerprovide feedback
