I'm in middle school but I don't even know what is thatttttt????
Hey bestie. There’s no picture to answer the question. Might have to re-upload this question.
Answer:
(a) 129600 J
(b) 81000 J
Step-by-step explanation:
The work done is given by the product of force and the displacement in the direction of force.
Force, F = 500 N
distance, d = 324 m
(a) friction force, f = 100 N
The work done is
W = (F - f) x d
W = (500 - 100) x 324
W = 129600 J
(b) Friction, f = 250 N
The work done is
W = (F - f) d
W = (500 - 250) x 324
W = 81000 J
50 seats = 25% = 1/4
100 seats = 50% = 2/4
150 seats = 75% = 3/4
200 seats = 100% = 4/4 <------ Logical pattern emerges.
Answer:
It's quite simple and there is no need for rounding, the answer should be <u>8ft</u>
Step-by-step explanation:
Here's why,
This problem can be solved with the Pythagorean Theorem, since in draws a triangle.
The picture should explain it, let's double check:
6^2+8^2=10^2
36+64=100
Looks like it checks out
