Question

Block 1,0,5 kg) travels with an initial velocity of 60) +[ 60 ) m/s and then com es block 2 (0.5 kg) tra eling th an tal velo ity of . -60 After the colision, block 1 has a final momentum o -10+ toj1kg*m/s. Assume that no external forces are present and therefore the momervtum for the system of blocks is conserved. What is the Initial momentum of block 17 What is the initial momentum of block 27 kg m/s Submit Answer Tries 0/3 What is the total Initial momentum of the system of blocks? kg*m/s Subeit Anawer Tries 0/3 What is the change in momentum for block 17 (notice that you are given the inal momentum for block What is the change in momentum for block 27 kg*m/s What is the final momentum of block 2 t Anse Tries 0/3 What is the total final momentum of he system of blocks i+ What is the total change of momentum of the system of blocks kg*m/ ut Anw Tries 03

Answer 1

Given is:-

mass of block 1 = 0.5kg

mass of block 2 = 0.5kg

Initial velocity of block 1 = 60i+60j m/s

Initial velocity of block 2 = -40i -60j m/s

Part-a

Momentum of an object is given by = mass * velocity

Thus the initial momentum of object 1 is

kg *m/s

Part-2

Initial momentum of block 2 is

kg*m/s

Part-c

TOtal initial momentum of the system is

which gives

kg*m/s

Part-d

Change in momentum is  

$\Delta p = p_{final} - p_{initial}$

thus

$\Delta p = (-10i + 0 j)- (10i + 0j)$

which gives

$\Delta p = -20i + 0 j$ kg* m/s
