Answer:
140 feet
Step-by-step explanation:
If the first time she dropped the ball was from 160 feet then the second time she dropped the ball is would bounce back up 80 feet. The third time it would bounce 40 feet. And the 4th time it would bounce 20 feet
So the total distance the ball traveled from the first time it hit the ground is 140 feet
I'm not 100% sure I understand the question but I tried
Answer:
The 38th term of 459,450,441,.. will be:

Step-by-step explanation:
Given the sequence

An arithmetic sequence has a constant difference 'd' and is defined by

computing the differences of all the adjacent terms

so

The first element of the sequence is

so the nth term will be


Putting n=38 to find the 38th term




Therefore, the 38th term of 459,450,441,.. will be:

Answer:
Step-by-step explanation:
Given
Restrained Force 
Increase in Kinetic Energy 
Distance moved d=1.9 m
Work done by all the forces is equal to change in Kinetic Energy of Object i.e. by gravity force, Normal force and Applied Force




(b)In absence of applied force thus
work done by gravity will be equal to change in kinetic Energy
change in Kinetic Energy
Answer:
2i or -2i
Step-by-step explanation:
2x² = -8 First, clear x.
x² = -8/2 Solve
x² = -4 Now, eliminate the square of x by solving the square root of -4.
x = √-4
x = 2i or -2i Is an imaginary number.
