The driver of a 1000 kg car is speeding. He loses control and collides with a wall, coming to a stop. The crumple zone of the car absorbed 90 kN of force in 0.5 seconds. What was the car's speed at the time of impact?

Answermake them get very hot and over time wear them out;

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 !
