During a period of accelerating from zero to 24 m/s, the average speed is 12 m/s.
Answer:
The speed of the piñata immediately after being cracked by the stick is .
Explanation:
Using the conservation of linear momentum:
(1)
Here:
m(s) is the mass of the stick
m(p) is the mass of the piñata
v(is) is the initial velocity of the stick
v(fp) is the final velocity of the piñata
So, we just need to solve the equation (1) to v(fp).
I hope it helps you!
