Question

lem 2. m v before after A bulet of mass m moving with velocity v, strikes auniform solid wheel of mass M and radius r and sticks to its outer rim. Let m 0.005 kg, v.-200 m/S7G0400,and r-o300 m A) What is the moment of inertia (in kg m2) of the wheel about its center before the bullt enters it? 0.018 b) 0.031c) 0.048 d) 0.071 0.30 0.01822 B) Find the angular velocity (in rad/s) of the system after the bullet enters the wheel a) 13.41 ,m 16.26 ,c) 15.74 ,d) 14.25/mv --mrv C) Find the angular momentum (in kg-m'/s) of the system about the anis after the collision. a) 0.494 b) 0.700 0.972 d) 0.300 Find the kinetic energy (in J) of rotation of the system about the axis after the bullet enters the wheel. D) a) 2.44 b) 3.88 4.99 d) 6.52 E) Find the loss of kinetic energy (in J) of system during the collision a) 97.6 b) 162 214 , d) 285 T U bi 845

Explanation / Answer

A) Moment of inertia = Mr^2 /2= .4 *(.3*.3) /2= 0.018
