In a physics lab experiment, a spring clamped to the table shoots a 22g ball horizontally. when the spring is compressed 21cm , the ball travels horizontally 5.0m and lands on the floor 1.7m below the point at which it left the spring.
what is the spring constant?
express your answer using two significant figures.

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 !
