Replacing these values:
So, the magnitude of the velocity is:
The angle of the velocity is:
Since on any collision, the velocity of the center of mass is preserved, then the velocity after the collision is the same as the previously calculated value of 16.66m/s at 59.0° due north of east
Answer:0.25 kg-m/s
Explanation:
Given
mass of blob
initial velocity
time of collision
we know Impulse is equal to change in momentum
initial momentum
Final momentum
as final velocity is zero
Impulse
