Question

B.C. O-850 JD. 0850 JE. O-765 J9. An object has a kinetic energy of 90 J as it crossesa location where its potential energy is 7 J.Calculate its mechanical energy as it crosses this location. (1 point)A. 097 JB. 091.3 JC. O 135.8 JD. O116.4 JE. 083 J10. Under the influence of conservative forces only.

Answer 1

9)

Mechanical energy = potential energy + kinetic energy

From the information given,

kinetic energy = 90

Potential energy = 7

Mechanical energy = 90 + 7

Mechanical energy = 97 J
