Question

A 1O.0g bullet is fired from a rifle having a barrel 0.60m long.Choosing the origin to be at the location where the bullet begins to move then, the force ( newton.) exerted by the expanding gases is given by : F(X) = 1.5 MULTIPLES 10 square 2 Nm)X - (2.4 multiples 10 square 2 Nm square 2) Xsquare 2 where X is in meters.Find the speed of the bullet as it leaves the barrel. A. draw, define and categorize quanities. B.what variables from the setup are you looking for?. C.use the quantities to solve the unknown defined in the setup. D. list and define the principles or laws used in solving B. E. Substitute values for knows into the solution from D. and calculate values for quantities from B. (

Explanation / Answer

W=Intedral(Fds), so you have to integrate the above equation from 0 to .6 in the fifst case and from 0 to 1 in the second

W = (15000x + 10000X^2/2 -25000x^3/3) from 0 to .6 = 9000J
W = (15000x + 10000X^2/2 -25000x^3/3) from 0 to 1 = 11.666J
