160j of work was needed in order to move an object 8m acroos a floor what was the force in N that was needed to do this job? i think it may be not sure but 20N dont agree with me just maybe your imput will be different
A screw is really an inclined plane wrapped around a cylinder.
you set up a pulley to help you lift something you anchor the rope at one end and arrange a moveable pulley to achieve a mechanical advantage of 2 by the time you have lifted the object 5m off the ground how much rope have you pulled through the pulley
answer is (10m)
The train has traveled along the track for 18 meters.
Multiplying and adding, the distance traveled is:
(1 x 20)m - (0.5 x 4)m
= 20 - 2
= 18
To calculate the distance traveled from a velocity-time graph, you need to calculate the area under the graph. The number of calculations you need to make, and the shapes you divide the area into will depend on the shape of the curve.
The skinnier you make the slices, and the more area measurements you make,
the more accurate your answer will be.
In the kind of math called "calculus", there's a way to work that problem as if the
width of the slices was zero and there was an infinite number of them, so that the answer comes out exactly right. It's called "integration."

There is a formula to calculate the speed of a car after accelerating for four seconds. This formula is v = u + at, where v = velocity, u = initial velocity, a = acceleration, and t = the time it takes to accelerate.
with regard to question 16 above could any part of the speed line ever become perfectly vertical
no acceleration
carve things
If a graph shows distance on the vertical axis and time on the horizontal axis, and the speed is steadily increasing, the line representing speed will be a straight line.
