An object of mass m = 6.05 kg has an acceleration a = (1.17 m/s2)x + (-0.664 m/s2)y.Three forces act on this object:F1,F2,and F3.Given that F1 = (2.96 N)X and F2 = (-1.55 N)x + (2.05 N)y,find F3.F3=( )X + ( )Y?

An object of mass m = 6.05 kg has an acceleration a = (1.17 m/s2)x + (-0.664 m/s2)y.Three forces act on this object:F1,F2,and F3.Given that F1 = (2.96 N)X and F2 = (-1.55 N)x + (2.05 N)y,find F3.F3=( )X + ( )Y? 英语翻译Newton's second law of motion describes force.It says:force equals the mass of an object,multiplied by the change in speed it produces in an object. SAT2物理题,涉及弹簧An object of mass m is attached to a vertically mounted spring that has spring constant k.The object is displaced from its equilibrium position and allowed to oscillate.Assume that air resistance and friction are negligible. 英语翻译1 the change in position of a body relative to others is called mechanical motion2 the point with mass an object is replaced by is called a mass point 3when we describe the motion of an object,any other object chosen as a reference is cal Object reference not set to an instance of an object. 英译汉The mass of an object is multiplied by the speed of light squared,没写完The mass of an object is multiplied by the speed of light squared, in other words , the speed of light is multiplied by itsel最后一句是by itself 英语高手的哥哥姐姐们,要怎么回答,1 What's the SI unit for force?2 what's inertia?3 what's the value of the acceleration due to gravity?4 how are the net force acting on an object,mass of the object and acceleration of the object mathema 英语翻译The gravity force of a space object depends on its mass.
