A person with a mass of 60kg is driving her car at a velocity of 30 m/s. The car is involved in a small collision and the airbag is deployed. The airbag provides a stopping force of 1200 N. The person’s final velocity is 0m/s. How long does it take for the person to be stopped by the airbag?

Occurs when an energy source transfers heat directly to another subject space; an example would be an object becoming warm by sitting in the sunshine

What is the force that opposes motion and works against the downward pull? a) friction b) gravity c) weight d) acceleration

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
