Answer:
109.6m/s
Explanation:
Given parameters:
Initial velocity = 100m/s
Acceleration = 10m/s²
Distance = 100m
Unknown:
Final speed = ?
Solution:
To solve this problem, we use the expression below;
V² = U² + 2aS
V is the final velocity
U is the initial velocity
a is the acceleration
S is the distance
V² = 100² + 2(10)(100)
V² = 10000 + 2000
V² = 12000
V = √12000 = 109.6m/s
Alright, so solving for the net force is a rather simple and easy step. I want to briefly explain how you determine the net force, but before I do, let's examine the problem together. What has been provided to us? What direction is it going? Well, we can look at the information!
Amanda's Force: 5 N
Jeremiah's Force: 10 N
They're both pushing on the books, but in different directions. Left and right. If Amanda is pushing the books to the right 5 newtons, and Jeremiah is pushing the books to the left with 10 newtons, that means the net force is 5. The book is being pushed to the left! We can say that because Jeremiah's force is much larger than his sisters.
We can determine the net force from the following;
Net Force → 10 N - 5 N = 5 N
In conclusion, your answer should be a total of five (5) newtons
Answer: 50m/s
Explanation: if you add 10 x 1 is 10 so you leave it as 10 then you do 10 x 5 which will come out as 50 so then you get the answer 50m/s
Answer: B. Community agencies
Explanation:
Family requires the services of community agencies for meeting their family and child needs. The community agencies provide with food items, dairy items, medicines, stationary stuff, clothes required as daily needs.
Answer:
a. about 20 years younger
b. Malcolm sits around for 49.94 years
c. <em>2.268x</em><em> m</em>
Explanation:
light travels 3x m in one seconds
in 20 years that will be 3x x 20 x 60 x 60 x 24 x 365 = 1.89x m
for the to and fro journey, total distance covered will be 2 x 1.89x = 3.78x m
Flo's speed = 80% of speed of light = 0.8 x 3x = 2.4x m/s
time that will pass for Malcolm will be distance/speed = 3.78x /2.4x
= 1575000000 s = <em>49.94 years</em>
the relativistic time t' will be
t' = t x
t' = 49.94 x
t' = 49.94 x 0.6 = <em>29.96 years</em> this is the time that has passed for Flo
this means that<em> Flo will be about 20 years younger than Malcolm when she returns</em>
<em></em>
relativistic distance is
d' = d x
d' = 3.78x x
d' = 3.78x x 0.6
d' = <em>2.268x</em><em> m</em> this is how far it is to Flo
