A bird flying horizontally accidentally drops a rock it was carrying. 2. 10 s later, the rock's velocity is 22.2 m/s in a -68.2 degrees direction. What was the bird's (and rock's) initial velocity? (Unit = m/s) (Hint: the rock was originally moving with the bird.)

2. they have negligible mass.

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 !
