A particle of mass 2kg is acted upon by a horizontal force of magnitude 10N for 8 seconds,in which time time it moves from rest until it is travelling with speed v米每秒.Show that v=40.The particle continues to move with this speed for the next 10 seconds.It is then brought to rest...
5. A particle is acted upon by two forces F and G. The force F has magnitude 8N and actsin a direction with a bearing of 240°. The force G has magnitude 10N and acts due South.Given that R=F + G, find(i) the magnitude of R,(ii) the direction of R, giving your answer ...

1). Now upon dividing the infinitesimal spatial coordinate interval dxα by this time difference the 3-velocity of a particle in the underlying spacetime is given by6,7 vα=dxαdτsy=dxαg00(dx0−gαdxα). (3) Figure 1 A congruence of nearby worldlines of fundamental observers and...
This is because conservative forces only affect the potential energy of a particle, not its kinetic energy. Therefore, the total mechanical energy (the sum of kinetic and potential energy) of a particle remains constant when acted upon by a single conservative force....
A particle with unit mass moves under the influence of a force F(t)=(et,t2,sin(t)). If V(0)=(1,2,5), find V(2). INewton's Second Law: Newton's Second Law of Motion states that the acceleration of an object is proportional to the net f...
