- Homework Statement
- What is the final velocity of a bullet given that its change in time is 0.1 seconds and F(t) = Fc(1+e^(-1the00t). The mass of the bullet is 20g.

- Relevant Equations
- Mvf - mvo = change in p = the integral of Fdt

Hi there,

Just asking a logistics question since I want to be sure I am approaching this problem correctly.

My professor showed me an example of a bullet being fired from a barrel, given its initial velocity was 0. The change in time was 0.1 seconds. The mass of the bullet is 0.02 kg. The equation he gave is F(t) = F

Since we know that MV

Only asking because I can't tell if it's just a ridiculously easy problem or I'm missing something.

_{c}(1+e^{(-100t)}), where F_{c}= 100N.Since we know that MV

_{f}- MV_{0}= Δp = ∫ Fdt, doesn't this mean I can set the given function equal to MV_{f}, since it is already force as a function of time (also since we know the initial velocity equals zero)? Or am I missing something?Only asking because I can't tell if it's just a ridiculously easy problem or I'm missing something.
