APSC 1023: Mechanics II Instructors: Michelle Kwok, Sadi Abujayyab Question 2 A 0.3 kg bullet is fired into a stationary 3.6 kg wooden block and becomes embedded in it. Find the initial velocity of the bullet and the impulsive force of the bullet on the block. (20 points) a) Sketch the momentum diagram for the bullet and the block before and after the collision. (3 points) Summer 2022 [email protected] b) Assuming momentum is conserved, what is the velocity of the bullet and block immediately after impact. (5 points) c) After the bullet hits, the block travels up the ramp and stops. Draw the impulse and momentum diagram of the bullet and block from the moment of impact to the moment they stop moving. Assume the coefficient of kinetic friction between the block and the ramp is uk-0.2. (5 points) d) Apply the principle of impulse and momentum to the block and bullet. (HINT: Consider the momentum of the block and bullet from the moment the bullet hits to when the box stops sliding). (5 points) e) How long does the block slide before it stops? (2 points) f) BONUS: What is the coefficient of restitution an indicator of? (1 point) 15% 300 m/s 30°
