A 6 kg red ball is moving at 4 m/s along the positive x-axis. The red ball elastically collides with a stationary 3 kg blue ball. After the collision, the red ball is traveling 2 m/s at 300° from the x-
axis. What is the magnitude of the blue ball's total final velocity?

This did i unseated, sorry

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 !
