Explanation:
Let us assume that piece 1 is 
is facing west side. And, piece 2 is 
facing south side.
Let 
= m and 
= 2m. Hence,
= 10.5 m/s
= 10.5 m/s
= 
= 14.84 m/s
or, = 15 m/s
Hence, the speed of the third piece is 15 m/s.
Now, we will find the angle as follows.
= 
= 
= 
Therefore, the direction of the third piece (degrees north of east) is north of east.
Answer:
Curves around objects
Explanation:
Diffraction is a property of light described by bending of light around an object. This ability of light to bend around edges has facilitated optical effects of light where there is interference of light waves. Other properties of light are: reflection, refraction, polarization, scattering of light, and interference of light.
Answer:
f = 25 lbs
m = 5 lbs
a =?
f = ma
25 = 5 a( divide both sides by 5)
a = 5(lbs)
