make a table for this

Make a Table The first two sentences tell you the speed of the ball at a given moment after launch. Use this information to create a velocity-time table. For instance, suppose it says the ball's speed is 20 m/s two seconds after launch and that the ball is moving upward. You then know that at 2 seconds, the object has a velocity of +20 m/s. Create a table that begins with that as one of the rows of the table. Fill in the rest of the table knowing that the velocity changes by -10 m/s for each second of motion. So v = 10 m/s at 3 seconds, v = 0 m/s at 4 seconds, v = -10 m/s at 5 seconds. Moving upward in the table from 2 seconds, we can say that v = 30 m/s at 1 second and 40 m/s at 0 seconds
