A 6450kg gorilla slides down the side of a 20m tall mountain at 47degrees. If the coefficient of kinetic friction is 0.23, what is the net work done on the gorilla? 80kg Keoni Mabini is pulled 33m up makakilo hill at 45 degrees by Brayden Pfister with aforce of 200 N. If the coefficient of kinetic friction between the Keoni’s okole and the hillis 0.11, what is the change in her kinetic energy?

Anilov rolls Brayden’s 3.5kg ball 10m. If she exerts force of 12N and the coefficient offriction between the ball and the ground is 0.31, what is the ball’s final speed?

PLEASE HELP ASAP

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

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?
