HI Dfgdfgdf
I would calculate it as follows....
The acceleration as the object decelerates is a = (initial velocity- final velocity / time)
The final velocity is at rest = zero
And the formula for Force is F=Ma where a is the acceleration and M is the objects Mass.
The acceleration is negative as it is de accelerating.
Therefore the Force = - Mass. (vel / time)
Another way to envisage it is with conservation of energy.....
W x D = F x R
where W= Weight, D= Distance to fall from Centre of Gravity, F = Retarding Force, R = retarding distance.
Hope these help !
