A 5 - kg blob of putty is dropped from a height of 10.0 m above the ground onto a light vertical spring the top of which is 5 m above the ground. If the spring constant k = 200 N/m and the blob compresses the spring by 1.50 m, then find the amount of energy lost in sound and thermal energy. a. 20 J b. 0.17 kj c. 0.27 kj d. 0.43 kj e. 94 J
