William wanghomework #33 regents review (3)0989assignment mode : open (time on task) 9 of 25 listenduring a collision, an 84-kilogram driver of a car moving at 24 meters per second is brought to rest by an inflating air bag in 1.2 seconds. the magnitude of the force exerted on the driver by the air bag is approximately7.0 × 101 n8.2 × 102 n1.7 × 103 n2.0 × 103 ntime on question: 00: 02: 59

Explanation:

The impulse theorem states that the product between the force and the time interval of the collision is equal to the change in momentum:

where

F is the force

is the time interval

m is the mass

is the change in velocity

Here we have

m = 84 kg

So we can solve the equation to find the force:

explanation:

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
