Hello, can you help me complete this table and answer these questions please? I don't know what I am doing. I will put the references below.

Post-Lab Questions

1. Use your predictions of velocity and range from the Pre-Lab Questions and the data recorded from your experiment to complete Table 4.

Table 4. Velocity and Range Data for all Ramp Distances

Ramp Distance (m)	Calculated velocity (m/s)	Predicted Range (m)	Average Actual Range (m)	Percent Error
48
25.5
12.5

1. How do your predictions compare to the observed data? Explain at least two reasons for the differences.
2. If you were to fire a paintball pellet horizontally and at the same time drop the same type of paintball pellet you fired from the paintball gun, which pellet would hit the ground first and why is this so?
3. Suppose you altered your existing ramp so that the marbles had twice their initial velocity right before leaving the ramp. How would this change the total distance traveled and the time that the marbles were in the air?
4. Describe the acceleration of the marble after it leaves the ramp. Use kinematic equations to support your discussion.

Reference:

The acceleration of the ball down the ramp is 9.81*sin()m/s² whereis the angle of the ramp 0=19.6dsin0

vertical= t= 2h/g

horizontal= V0x=2h/g
