1.	A bullet is fired with a velocity of 380 cm per second into a wooden block of thickness 0.19m.it emerges with a velocity of 1.2 metre per second find the acceleration of the bullet
Answer» $\huge\underline{\underline{\bf \orange{Question-}}}$ A bullet is fired with a velocity of 380 cm per second into a wooden BLOCK of thickness 0.19m.it EMERGES with a velocity of 1.2 metre per second FIND the ACCELERATION of the bullet $\huge\underline{\underline{\bf \orange{Solution-}}}$ $\large\underline{\underline{\sf Given:}}$ Bullet fire with Velocity ${\sf (u)=380m/s}$ Convert it into m/s $\implies{\sf u=\dfrac{380}{100} }$ $\implies{\sf u = 3.8m/s }$ Wooden block of thickness (s) = 0.19m It emerges with velocity (v) = 1.2m/s $\large\underline{\underline{\sf To\:Find:}}$ Acceleration of bullet (a) ✪ $\large{\boxed{\bf \blue{v^2-u^2=2as }}}$ $\implies{\sf (1.2)^2-(3.8)^2=2×a×0.19}$ $\implies{\sf 1.44-14.44=0.38a}$ $\implies{\sf 0.38a=-13}$ $\implies{\sf a=\dfrac{-13}{0.38}}$ $\implies{\bf \red{Acceleration ( a) = -34.2m/a^2}}$ $\huge\underline{\underline{\bf \orange{Answer-}}}$ Bullet will retar d by ${\bf \red{-34.2m/s^2}}$ .
