Answer:
767.6 m/s
Explanation:
We consider momentum in both x and y components
Since momentum, p=mv where m denote mass while v is velocity then
In the y direction
3m*288=279m+my
y=585 m/s
In the x direction and taking right as positive then
3m*288=367m+mx
x=497 m/s
The resultant gives the velocity of the third fragment

Answer:
The first answer is W and Z, since they appear to be a period apart. Dont know the second question. I did what I could, hope someone can answer the second.
Answer:
1.884 meters per second
Explanation:
s = d/t
d = C = 2πr = 2π(6) = 37.68 m
t = 20 s
s = (37.68 m)/(20 s)
s = 1.884 m/s
I believe the answer is resonance
