Answer:
The average velocity is 2 m/s.
Explanation:
The velocity of the particle is the time derivative of its position
Now the average from and is
Thus, the average velocity is 2 m/s.
Answer:
64.5
Explanation:
(m1 + m2) v initial = (m1 * v1 final) + (m2 * v2 final)
(92 + 8)(-7) = (92 x 2) + (8 x v2 final)
(100)(-7) = (184) + (8 x v2 final)
-700 = (184) + (8 x v2 final)
-516 = (8 x v2 final)
-516/8 = v2 final
-64.5 = v2 final
