what is the minimum amount of energy required to accelerate horizontally a 3.0g bullet from rest to a speed of 40.0 m/s?

  • PHYSICS HELP -

    what is 1/2 mass*velocity^2

  • PHYSICS HELP -

    so is it 1/2(3)(40)^2?

  • PHYSICS HELP -

    no, no, no. mass has to be in Kilograms.

  • PHYSICS HELP -

    oh right. so 1/2(.003)(40)^3
