The change in momentum (and impulse) are still 3000 N*s. Safety devices (like airbags, seatbelts and crumple zones) cause crashe

s to take more time to occur. Now the crash takes 1.5 seconds. How much force is exerted on you in this case? *

Answer:

F = 2000 N

Explanation:

According to Newton's Second Law of Motion, the rate of change of momentum is equal to the force applied. Therefore, the formula written below will be used to solve this problem:

$F = \frac{\Delta P}{t}\\\\$

where,

F = Force everted = ?

ΔP = Cange in Momentum = 3000 N.s

t = time taken = 1.5 s

Therefore,

$F = \frac{3000\ N.s}{1.5\ s}$
