Me to solve this.
an automobile, the speed of which is increasing at a rate of 6.0 m/s2, travels along a circular road of radius 20m. when the instantaneous speed of the automobile is 4m/s find (a) the tangential acceleraction components and (b) the magnitude and direction of the total acceleraction

The most important difference between a wedge and an inclined plane is a. their size b. their shape c. how they are used d. what they are made of

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
