When k.E. Of the body is increased by 300% , the momentum of body is increased by:? |
|
Answer» crease in momentum100% KE (normal) + 300% KE (increase) = 400% KE or 4xKEKE = (1/2)*m*v^2define initial and final states...4X KE1 = KE2 4x (1/2)*m1*v1^2 = (1/2)*m2*v2^2cancel out (1/2) factormass doesn't change, m1 = m2 = m..... cancel out m 4v1^2 = v2^2 or (2v1)^2 = v2^22*v1 = v2momentum is P = mvm*v1 + Pchange = m*v2 = m* (2v1)Pchange = 2*m*v1 - m*v1 = m*v1m* v1 is 100% of m*v1momentum is increased by 100%I hope this will HELP youIf not then comment me |
