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
The equations are

Answer:
D. Salt Weathering
Explanation:
Salt weathering is defined as a geomorphic process resulting in the physical disintegration of rocks or stones and in the fretting of their surfaces. Often you tend to find the best examples of salt weathering in dessert areas and coastal areas. You can find three distinct types of weathering which are biological weathering, physical weathering, and chemical weathering.
