A bullet of mass 45 g hits a block of mass 3.66 kg with a speed v. After the collision, the bullet emerges at the other end of the block with a speed of 87 m/s, and the pendulum swings up over an angle of 38°. If the string of the pendulum is 3.6 m, what was the initial speed v of the bullet? st

Answers

Solution : - mas = m = of bullet 45x10 45g 3M = 3.60 Ry mas of bloch initial velocity of bulket = v final velocity of that -2. 1,2 = 7.6 X10% + 1.22 x103 2 U? = 8.82 X 103 V 93.92 m/s to initial velocity of bullet deullet was 93.92 mle
