    Physics (Conservation of Energy)
    A 100g arrow is pulled back 75cm with an average force of 290N, aimed upwards, and released. Use the law of conservation of energy to solve these problems.

    a) Neglecting air resistance, how high should the arrow go?

    b) If the arrow went up 149m, how much work was done against air resistance?

Conservation of Energy With a Swing [ 1 Answers ]

a. 0 + mgh = 1/2mv^2 + 0 1/2mv^2 = mgh v=sqrt(2gh) = 3.43 m/s b. I'm not sure how to do this, so I had to hazard a guess: KE top + PE top = KE bottom + PE bottom + Work of friction => 0 + mgh = 1/2mv^2 + 0 + Wf => mgh - 1/2mv^2 = Wf

Is there no energy conservation [ 2 Answers ]

When we look at a particle's rest frame its energy is Mc^2. But the particle decay has some width, so the products of the particle,generally, will have total energy different than Mc^2. How can it be, is there no energy conservation.
