Answer:
x = 0.0873 m
Explanation:
given,
length of clothesline = 10 m
the line sags to create an angle that is 1 degree below the horizontal on each end.
As mass is hang at the center the angle made let the deflection be 'x'
as the shirt is hang at the center distance will be equal to 5 m.
now
x = 0.0873 m
Hence, the cloth line will be x = 0.0873 m from the original length of the clothesline.
C. The Densities are equal.
<h3>What is density?</h3>
Density is mass per unit volume or mass of a unit volume of a material substance.
If m1, V1 and D1 = mass, volume and density respectively of ball C
m2, V2 and D2 = mass, volume and density respectively of ball D
According to the Question ,
Therefore,
Hence, D1 = D2

The concept that we need to give solution to this problem is collision equation given by momentum conservation,
Our values are,
Then,
Part A) We can here note that the velocity for the puck is zero (there is not a velocity in that direction)
Part B ) We apply the same solution but know we note that in the collision for the Goalie the velocity is zero.
