A 0.60-kg sheet hangs from a massless clothesline as shown
Chapter 3, Problem 14P(choose chapter or problem)
A 0.60-kg sheet hangs from a massless clothesline as shown in Fig. 9–48. The clothesline on either side of the sheet makes an angle of \(3.5^{\circ}\) with the horizontal. Calculate the tension in the clothesline on either side of the sheet. Why is the tension so much greater than the weight of the sheet?

ANSWER:SOLUTION:Step 1 of 3 The momentum is quantity of measurement of motion of object.Mathematically, p=mv In an isolated system , the total momentum is conserved because there is noexternal force acting on it .Consider two bodies Initial momentum of the bodies before collision p and p res1ectively2 final momentum of the bodies after collision p 1and p 2 respectivelyFrom newton's second law dpF= dt p1 1 Force exerted on 1 by 2 ,F = 12 t Force exerted on 2 by 1 ,F = p2 2 21 t By newton's third lawF 12F 21p11 = (p2 2 ) t t p - p =(p - p ) 1 1 2 2 p1- p 1p 2 + p 2 p1- p 2=p +1p 2This is law of conservation of momentum
