The kinetic energy of the arrow when it is about to hit the ground is 34.7 J.

The given parameters;

  • elastic potential energy of the arrow, Ux = 34.3 J
  • gravitational potential energy, P.E = 0.4 J

According the principle of conservation of energy, the total potential energy of the arrow will be converted to maximum kinetic energy when the arrow is about to hit the ground.

[tex]K.E = P.E + U_x\\\\K.E = 34.3 \ J \ + \ 0.4 \ J\\\\K.E = 34.7 \ J[/tex]

Thus, the kinetic energy of the arrow when it is about to hit the ground is 34.7 J.
