Answer:
<em>10.09 units</em>
Explanation:
For the A
Ax = -8.0 units
Ay = 6.0 units
The resultant vector = Ra =
Ra = = 10 units
For B
Bx = 1.0 units
By = -1.0 units
The resultant vector = Rb =
Rb = =
units
Adding these two vectors A and B together, magnitude of vector R is
R =
R = = <em>10.09 units</em>
Answer:
Explanation:
Puck A's initial speed is and move in a direction
after the collision.
# since there's no external force on the system(
#The collision equation can be written as;
The kinetic energies before and after the collision are expressed as:
Let +x along A's initial direction and +y along A's final direction makes the angle
#Substitute in :
Hence, the the speed of puck A after the collision is 12.891 m/s
#. The velocity of A after the collision is;
Substitute into
:
This is the velocity of puck B after the collision, it's speed is:
The velocity of puck B after the collision is 6.8544 m/s
c. The direction of puck B after the collision is:
Hence, the direction of B's velocity after the collision is 62°
