A person has a reasonable chance of surviving an automobile crash, automobile crash of the deceleration is no more than 30 gs.
00:07
So can we get the force on a 65 program person accelerating at this rate? what is the distance is traveled if it is brought to rate, to rest at this rate from 95 km per hour? all right, so we have to find the force.
00:22
So the force is definitely equal to ma, so mass is 65, and acceleration is 30 g, so 30 g.
00:29
G means 30 times 9 .8.
00:32
So let me calculate this one from the, let me use the calculator.
00:36
So 65 times 30 times 9 .8.
00:40
It's going to be 1911110, newton's.
00:46
And we have to find the value of the distance travel.
00:50
So the distance traveled is going to be, we're going to use the third equation of motion.
00:53
So v .2 is going to v .0 square plus 2 a.
00:57
The final speed is zero...
