A 65kg person traveling at 29m/s (65mph) collides head on with a jersey barrier. How much force in Newtons is experienced by the driver if they hit the airbag for 1s?

mass of person m=65kg
speed of person u=29m/s
after colliding with bat person comes to rest so final velocity v=0
time duration in which pesrson interact with airbag and comes to rest t=1s
accelration of person
here negative sign shows the acceleration in opposite direction of initial velocity.
we know F=ma
F=-1885N
again negative sign shows that force is experienced in opposite direction of motion.

- A commercial airplane is coming in for a landing. Just before it hits the runway it is moving at 76 m/s. The plane has a mass of 20,000 kg. The runway is 1.6km long and, obviously, the airplane needs to be stopped before it reaches the end of the runway. How large is the braking force the airplane needs to stop safely before the end of the runway?A car traveling at 27.2 m/s hits a bridge abutment. A passenger in the car, who has a mass of 65.0 kg, moves forward a distance of 57.0 cm while being brought to rest by an inflated air bag. Assuming that the force that stops the passenger is constant, what is the magnitude F of this force?The froghopper holds the title of the best jumper of the animal world.
