V= 2u+at+v = 1+a = -7+t = 12 From the above relation, there are few things clear that: V = 12 ----- eq(1), -7+t = 12 Or, t= 12+7 = 19----eq(2) And, 1+a= 12 Also, a = 12-1= 11-----eq(3) So v = 12, a = 11 and t=19------eq(4) Put the values of v, t, and a from eqs 1, 2 and 3 in v = 2u+at+v This becomes, 12 = 2u+(11)(19)+12 Now solve for u gives u=-209/2 = -104.5 Thus, v= 12, a= 11, t= 19 and u= -104.5 (solved😊)
