The force acting on a object ( 10 kg ) as function of time is given by : F (t) = [ (-20t + 90)i - 60j + ( 10t + 40)k ] Newton At time t=0 seconds , the speed of the object is given by : V = [-14i + 26j + 32k ] m/s question a ) use the impulse-momentum theorem for deciding the...

Hi A block ( 0.5 kg ) is attached to a spring ( k = 40N/m ) on a frictionless table.. The spring is 0.6 meter long unstretched .. A constant force (20 N ) is applied horisontaly causing the spring to stretch 1) question : what is the speed/velocity of the box after 0.25 meter ...
