QUESTION 4 3 points Save Answer Vic Beasley (m 102 kg) sacked Braxton Miller (m- 98 kg) a few times during the Discover Orange Bowl. Suppose that Vic is chasing Braxton at 0.25 m/s while Braxton, trying to avoid the sack and gain positive yards, runs forward at-0.2 m/s. After the collision, Braxton's final velocity is 0 m/s. What is Vic's final velocity? You may assume that the two are running in a straight line towards each other. Hint: start by drawing a picture of the situation and writing the conservation of momentum in terms of the masses and velocities. You do not need to include units in your submission. Yo QUESTION 5 3 points Save Answer Consider a bomb of mass M (see figure below) that sits in the middle of space. Initially, the bomb is at rest. What is the momentum of the bomb? You do not need to input units with your answer.

Explanation / Answer

4.

use conservation of momentum:
m1*v1i + m2*v2i =m1*v1f + m2*v2f
102*0.25 + 98*(-0.2) = 102*v + 98*0
102*0.25 + 98*(-0.2) = 102*v
5.9 = 102*v
v=0.06 m/s

5.
Since bomb is at rest, its initial momentum = 0
since momentum = mass* velocity and velocity is 0 here
Answer: 0

6.
Use conservation of momentum:
final momentum of system=initial momentum of system
final momentum of system= 0
since final momentum of system=0
Answer: 0
