Question

An object having mass 1400 kg. The two objects stick together. Find (a) the speed and (b) the mass of the composite object.

Answer 1

Given One mass m1 = 900 Kg And other mass m2 = 1400 Kg a)We know that m1v1 m2 v2 = mv Therefore v = (m1v1 m2v2)/m = (900 *0.850 0)/ 2300 ( because m2 is stationary so velocity = 0) So v = 765/ 2300 =...
