Question

lasie10. Under the influence of conservative forces only,an object is displaced from point A to point B.Its potential energy and kinetc energy at point A arerespectively 64.343 J and 30.434 J. Its kinetic energy at point B is10 J. Calculate its potential energy at point B. (1 point)A. 037.562 JB. 084.777 JC.58.407 J120 747 T

Answer 1

10)

Since the system is conserved, the sum of the potential and kinetic energy would always remain the same.

From the information given,

potential energy at point A = 64.343

Kinetic energy at point A = 30.434

Total energy = 64.343 + 30.434 = 94.777

Total energy at point B = total energy at point A = 94.777

Given that kinetic energy at point B is 10J,

Potential energy at point B = 94.777 - 10

Potential energy at point B = 84.777 J
