Answer:
The correct answer is option b.
Explanation:
In velocity vs time graph, vertical axis represent velocity vector and horizontal axis represents time. The slope of the line obtained in this graph is equal to the acceleration.
- If the line is straight makes an acute angle with horizontal axis then it is considered as positive acceleration.
- If the line is straight makes an obtuse angle with horizontal axis then it is considered as negative acceleration or deceleration.
Answer:
p_k=\sqrt{p_x^2+p_y^2}}
Explanation:
Apply the momentum in each direction knowing that the impact is at the same time for the pieces so
So the momentum in the other piece can be find knowing that
So:
To find the velocity knowing the mass
