2. (Kinetic Energy and Work) An object having a mass of 2 kg, which is initially at rest at point A, starts its motion along frictionless path of A-C and finally, stops momentarily after it compresses the spring (k = 100 N/m) by r m. Takeg= 10 m/s. %3D i Find the compression distance, r, if angle 0 of the inclined plane is d=10 m B. 30° and the distance travelled on in- clined plane, d, just before hitting the spring is 1.0 m. 4.5 m ii The object starts moving in opposite direction after it stops momentarily. What is the speed of the object just after it starts its motion in opposite 4.0 m direction? iii Determine the final position of the object at the end of motion in op- posite direction along path C – A. Answer: i) r = 0.5 m ii) v= 5 m/s iii) A 2.
