1. The problem statement, all variables and given/known data 2. Relevant equations ΣF=ma FF=μFN impulse=ΣFΔt momentum=mv ΣFΔt=mΔv 3. The attempt at a solution This is where I got stuck... How can I solve for impulse without time or velocity? Is there a way to manipulate the equations to love for either time or velocity?
