A. The height above the ground reached by the mass is 2.3 m.

Height traveled by the mass

P.E = mgh

where;

  • m is mass
  • h is height reached by the object
  • g is acceleration due to gravity

h = P.E/mg

h = (342)/(15.2 x 9.8)

h = 2.3 m

Thus, the height above the ground reached by the mass is 2.3 m.
