Aball is hit straight up with an initial speed of 28 meters per second. what is the speed of the ball 2.2 seconds after it is hit? [neglect friction.]

By neglecting friction, the final velocity of the ball thrown upward with an initial speed of v₀ can be calculated through the equation,
                                          vf = v₀ - gt
where vf is final velocity, g is acceleration due to gravity and t is time. Substituting,
                                         vf = 28 m/s - (9.8 m/s²)(2.2. s)
                                           vf = 6.44 m/s
Thus, the final velocity of the ball is approximately 6.44 m/s. 

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.
