Answer:250 N
Step-by-step explanation:
Given
mass of skater on left side
mass of skater on right side
If the skater on the left experience a force of
If they push against each other then they must experience an equal force according to newtons third law
Thus
Thus skater on right experience force
Given:
Growth rate = 30% decrease
To find:
The growth factor associated with the given growth rate.
Solution:
The general exponential function is:
Where, a is the initial value, r is the growth rate in decimal and is the growth factor.
It is given that the growth rate is 30% decrease. So,
Now,
Therefore, the growth factor is 0.7.
