How high should a 2 kg mass be lifted from the ground if it is thrown upward at speed of 15 m/s? (Assume g = 10 m/s) no links please ​

Respuesta :

The height reached by the object above the ground is 11.5 m.

The given parameters:

  • Mass, m = 2 kg
  • Speed of the object, v = 15 m/s

What is principle of conservation of energy?

  • The principle of conservation of energy states that, the total energy of a system is always conserved.

P.E = K.E

mgh = ¹/₂mv²

gh = ¹/₂v²

[tex]h = \frac{v^2}{2g} \\\\h = \frac{(15)^2}{2(9.8)} \\\\h = 11.5 \ m[/tex]

Thus, the height reached by the object above the ground is 11.5 m.
