If a graph shows time on the horizontal axis and speed on the vertical axis a straight horizontal line across the graph would indicate

constant speed

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 gro

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)

With regard to the object-lifting examples traced in lesson3 the ima is equal to the distance divided by the distance

it effort,resistance

What is the effect of using an inclined plane to lift an object

no

A graph shows distance on the vertical axis and time on the horizontal axisif the speed is steadily increasing what will the line representing speed look like on the graph

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.
