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

Heat loss in this process is given as 93.8 J

Explanation:

As we know that the initial total energy of the blob is in the form of gravitational potential energy

So initial total energy is given as

Final total energy of the blob + spring is given as

now we have

what best describes physical development during adolescence is the development of secondary sex characteristics happens at a rate unique to each individual.

that would be because of both gravity and friction. so     c
