Question

How much impulse is needed to stop a ball that is 1.0 kg in mass and 9.0 m/s in speed?
Please explain how you figure it out so I can do other ones similar to this.

Answer 1

For Solving this Question, I would like to ask you that, do you have the detailed conception of : impulse

Answer 2

stop==> final velocity =0ms-1
so, by \(F=\frac{m(v-u)}{t}\), where impulse=Ft=m(v-u),
sub everything in.
do you need further help?
