Answer:

D. 50 J

hope it helps you you just need to put the values or substitute the value in me=ke+pe

Answer:

D.[tex]\pmb{ 50~J}[/tex]

Explanation:

As we know that [tex]\sf{M_{E}=K_{E}+P_{E} }[/tex]

where,

  • ME=mechanical energy
  • KE=kinetic energy
  • PE=potential Energy

According to the question

  • ME=KE+PE

  • ME=40J+10J

  • ME=50J
