2 (a) State the law of conservation of linear momentum.___________[2]___(b) A bullet of mass 0.02 kg travelling horizontally with a speed of 500 m si1 becomes embedded in a bag of sand of mass 40 kg initially at
Statement : In an isolated system of collision of bodies, the total linear momentum before impact is equal to the total linear momentum after impact. Let m(1) and m(2) be the masscs of two bodies moving along vecv(1i) and vecv(2i). Let vecv(1f) and
(a) State the principle of conservation of linear momentum. 相关知识点: 试题来源: 解析 The total momentum of a system (of colliding particles) remains constant [M1] Provided there is no resultant external force acting on the system /isolated or closed system [A1] ...
According to Newton's second law of motion, the conservation statement for linear momentum is expressed as time rate of change of linear momentum of a body equal to the forces acting on a body. In the case of an accelerating sphere, an additional force called "fluid inertia" force acts ...
Conservation of momentumConservation of thermal energy65N3065N1265N1535Q79In this work we present a new mixed finite element method for a class of steady-state natural convection models describing the behavior of non-isothermal incompressible fluids subject to a heat source. Our approach is based ...

Newton's law of viscosity relates shear stress τyx, which is the force in the x direction on a unit area perpendicular to the y direction, and the velocity gradient in a Newtonian fluid, and is given for a one-dimensional flow as Sign in to download full-size image Fig. 3. Steady ...
When the extension of the spring becomes zero. block A has speed v A and block B has speed VB.For the instant when the extension of the spring becomes zero,(i) use the conservation of momentum to show that kinetic energy of block A =1.5kinetic energy of block B(ii) use the ...

However, the basic gasdynamic equations, that is, the laws of conservation of mass, momentum, and energy, are nonlinear partial differential equations of second order and are in general not solvable in a closed analytical form, except for a one-dimensional unsteady flow. Fortunately, it is now...
