Question

Question 1 5 pts In a ballistic pendulum, a bullet of mass m is fired into a stationary hanging block of mass M. On impact, the bullet is trapped inside the block, which then slides up to a maximum height of h - 11.26 cm. If the mass of the block (M) is 2.3 times larger than the mass of the bullet (m), determine the speed v which the bullet must have had prior to impact. M+m m

Answer 1

& Given date & h = 11.26 cm M = 2.3 m speed o, when 11.26 cm from collision o 1 / (mt my re² = (m + M) gh i. v = (@gu)!? = V2x9.8 x 11.26 X10-2 .. o = 1.48 mis point of

=) speed & which the bullet must have had prior to impact , muo to = m +M) % Vo=(m. + M) olm = (m + 2.3m) 1.481m i. Vo = 4.88 misee
