The bulletpenetrates for a distance of 0.0621 m. Determine the acceleration of the bullet while moving intothe clay. (Assume a uniform acceleration.) |

Answer» The speed of bullet, U: 367m/s The DISTANCE traveled before the stop, S: 0.0621 m Assume that ‘a’ is the acceleration of bullet so the equation would be, if bullet COMES to rest, v^2 = u^2 +2aS 0 = 367^2 + 2a x 0.0621 a = -1094452.5 m/s^2 so the negative SIGN DENOTES that the acceleration is directed opposite to the motion of bullet. Jope it helps u. |
