Collar b moves to the left with a speed of 5 m> s, which is increasing at a constant rate of 1.5 m> s2, relative to the hoop, while the hoop rotates with the angular velocity and angular acceleration shown. determine the magnitudes of the velocity and acceleration of the collar at this instant.

Which quantities are scalars? choose all that apply a.distance b.speed c. acceleration d.velocity

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
