Answer:
The constant force exerted on the ball by the wall is 119.68 N.
Step-by-step explanation:
Consider the provided information.
It is given that the mass of the ball is m = 2.2 kg
The initial velocity of the ball towards left is 7.4 m/s
So the momentum of the ball when it strikes is = 
The final velocity of the ball is -6.2 m/s
So the momentum of the ball when it strikes back is = 
Thus change in moment is: 
The duration of force exerted on the ball t = 0.25 s
Therefore, the constant force exerted on the ball by the wall is:

Hence, the constant force exerted on the ball by the wall is 119.68 N.
Answer:
c
Step-by-step explanation:
A(-7,-4) B(-2,0)
√[(x'-x)^2+(y'-y)^2]
√(-2-(-7)^2+(0-(-4)^2
√(5^2)+(4^2)
√25+16
√41
the distance is approximately 6.4 units
Amount of wax required for one orange crayon is 0.22 pounds.
Step-by-step explanation:
According to given statement;
22 pounds of wax = 100 orange crayons
For calculating wax for one crayon;
Wax required for one crayon = Total pounds of wax / Total no of crayons
Wax required for one crayon = 
Wax required for one crayon = 
Amount of wax required for one orange crayon is 0.22 pounds.
