1. The problem statement, all variables and given/known data a) Given: 2ad - Vf2 - Vl2 . Find Vl? b) Given: KE = 1/2 mv2 . Find V? c) Given: a= (Vf - Vl)/t Find Vl d) d= 1/2 gt 2 find t? e) ac= (mv2)r, find M? 2. Relevant equations sorry, i do not know what are relevant eqs. 3. The attempt at a solution i have answeres a,b,c but i do not know the rest. 1) Vl =v2 - 2ad Vl= sqrt(v2-2ad) 2) v2 = (2KE)/m V= sqrt(2KE)/m 3) Vf = Vl + at Vl = V - at Thanks.
