Answer:

3500N

Explanation:

Given parameters:

Mass of driver  = 50kg

Speed  = 35m/s

Time  = 0.5s

Unknown:

Average force the seat belt exerts on her = ?

Solution:

The average force the seat belt exerts on her can be deduced from Newton's second law of motion.

   F = mass x acceleration

So;

     F  = mass x  [tex]\frac{change in velocity }{time}[/tex]

  F  = 50 x [tex]\frac{35}{0.5}[/tex]    = 3500N
