Can you answer demonstration 5

Thank you!!

Demonstration 4: The positive direction is to the right. A crate is on the surface of a frozen lake so that friction is very small. The crate is given a brief push to the right and then released. Sketch on the axes on the right your predictions of the velocity and applied force for the motion, including the time during the push. Is the net force the same as the applied force in 0 velocity time this case? Only after you have made your prediction, open the simulation Forces and Motion: https://phet.colorado.edu/sims/cheerpj/motion-series/latest/motion-series.html?simulation=forces-and-motion applied force time To set up to graph Force and Velocity click on FORCE GRAPHS and then Velocity+. Click on the X to get rid of the barriers. On right check Ice (no friction) and Choose Small Crate as the object. Use the slider to set the Position as far to the left as possible. Set the force to +200 N by typing 200 in the box and then click . As the crate starts moving to the right, immediately type 0 in the FApplied box, and after 3 sec hit Return to change the applied force to zero. When the crate reaches the right side click " to stop graphing. Compare the resulting graphs to your predictions and explain any differences. After the force is no longer applied (reduced to zero) does the crate still move? Why? How is this related to Newton's First Law? Demonstration 5: The positive direction is to the right. The frictional force acting on the crate remains very small (almost no friction) and can be ignored. The crate is given a push toward the right and released After it is released, a constant force velocity pushes on it to the left. It moves to the right, slowing down at a steady rate (constant acceleration), comes to rest time momentarily and then moves to the left, speeding up at a steady rate. Sketch on the axes on the right your predictions of the velocity and acceleration and of the force on the crate after the crate is released. Only after you have made your predictions, use the same simulation, Forces and Motion, to test them. acceleration First click Reset All and Yes. To set up to graph Force, Velocity and Acceleration click on FORCE GRAPHS and then ime Acceleration+ and Velocity+. Get rid of the barriers, check Ice (no friction), Choose Small Crate and set the Position as far to the left as possible. Set the force to +500 N and then click . Immediately type -500 in the FApplied box, and after 2 force sec hit Return to change the applied force to 500 N toward the left. When the crate reaches the left side again, click to time stop graphing. Compare the resulting graphs to your predictions and explain any differences. Why is the net force on the crate essentially the same as the applied force in this case? How does the acceleration at the point the crate reverses direction compare to the acceleration before it reverses direction? After? Explain. How does the force at the point the crate reverses direction compare to the force before it reverses direction? After
