Answer :
302 m/s^2
To rephrase this problem. We want to know the acceleration it takes to change velocity by 6.5 m/s over a distance of 70mm, or 0.070 meters. We can solve this problem a couple of ways, but for this problem, I'm going to redefine it in terms of work which is force over distance. So let's see how much energy the item has
E = 0.5*M*V^2
E = M*0.5*(6.5 m/s)^2
E = M*0.5*42.25 m^2/s^2
E = M*21.125 m^2/s^2
Now for the work needed
E = M*F*D
M*21.125 m^2/s^2 = M*F*0.07m
21.125 m^2/s^2 = F*0.07m
301.7857143 m/s^2 = F
So the object underwent an acceleration of 302 m/s^2
