A car crashes into a wall a 25m/s and is brought to rest in 0.1s. Calculate the average force exerted on a 75kg test dummy by the seat belt.
What is the formula to solve this problem.

Dr Russ,
Try to think a problem through, rather than looking for an equation to post values into.
Here you need the force on the dummy, one way to calculate force is
F=ma
where m=mass and a=acceleration
the question gives you the mass of the dummy. How do we calculate the acceration from the data given?
