A stone is thrown vertically upward with the velocity of 40m/s find the velocity of stone after 1.5s ii the time taken by the stone to reach the maximum height iii the total distance travelled by the stone before it returned to the earth surface urgent ​

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.

That depends on what kind of environ meant it is in  in space it has the same force that was applied when the velocity was gained
