Un bloque de mA = 5,00 kg colocado en reposo sobre una mesa rugosa con coeficiente de rozamiento cinético 0,200, inclinada 30,0° respecto de la horizontal, está conectado a un cable cuya tensión es de 60,0 N, que pasa por una polea sin fricción y luego se fija a un bloque de mB como se muestra en la figura. Determine el trabajo realizado por la tensión que actúa sobre el bloque B, cuando recorrer los 2,50 m.

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
