How much work must be done to accelerate a 1.0g insect from rest up to 12 m/s?

Question

Don't you need time to get acceleration, and therefore force? (W=fd)

Answer 1

This is not an acceleration problem.

W = KE = ½mv² = ½*.001*12² = .072 J

Answer 2

W = KE = 1/2 m v^2

As long as it got up to 12 m/s, it will have the same energy.

= .072 J
