Truck overtakes carYou used a combination of three tracks to simulate the problem in which a car passes before I pull out in my truck.
Insert a copy of your data here, along with any previously submitted work you wish to include:
In this lab we were given a situation with a car and a truck going down a ramp. If the car is released 10cm before the truck when will their speeds match? And when will the truck overtake the car? We then calculated the acceleration, initial and final velocities and change of time. We also made a graph for each question after all the calculations were found.

@&
You haven't reported data. The data consist of everything you measured and observed. All your data should be reported here for easy reference.
*@
Explain how you positioned the ball representing the truck, the ball representing the car, and how you timed the release of each.
We placed the truck 10cm in front of the car and released the car first, then released the truck when the car passed its position.
#$&*
According to your data what was the velocity of the ball representing the car at the instant it passed the position of the ball representing the truck?
It was constant at 10 cm/s.
#$&*
According to your data what was the acceleration of the ball representing the truck?
The truck was accelerating at 20 cm/s^2.
#$&*
According to your observations, what were the positions of the two balls when their velocities matched?
The truck will be 2.5cm down the ramp and the car will be 15 cm down the ramp.

@&
This seems reasonable but you haven't explained how this is connected to your data. You need to show the connection and how it was calculated.
*@
According to your previously calculated accelerations and velocities, what were the positions of the two balls when their velocities matched?
When the truck is 2.5cm down the ramp the car will be 15cm down the ramp.
#$&*
According to your observations, at what position did the ball representing the truck overtake the ball representing the car?
When the distance of the car from the initial point equals the distance of the truck from the initial point.
#$&*
@&
Did you observe the positions of the two balls when this occurred? This would have been part of your data.
*@
According to your previously calculated velocities and accelerations, at what position should the ball representing the truck overtake the ball representing the car?
When the distance of the car from the initial point equals the distance of the truck from the initial point.
#$&*
@&
According to the velocities and accelerations you used earlier, where would this occur?
*@
@&
You need to show how this could be calculated based on those velocities and accelerations.

You need to clearly report your data and show how the data were used to obtain your results.
