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 rm. Take g = 10 m/s2. i Find the compression distance, r, if angle 0 of the inclined plane is d10 m 30° and the distance travelled on in- clined plane, d, just before hitting the spring is 1.0 m. 4.5m 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 direction? 4.0m 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 %3D 2.
