Include your drawings for five additional pieces of equipment here and include a prediction for each, identifying how you think it could be used in a physics experiment. For example, what physics topic might a ramp help demonstrate? What lab safety precautions will need to be considered?

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)

Anybody wanna ? (picture included? )

There are two-speed cameras, one in an are where the speed limit is 30 km/h and another where the speed limit is 50 km/h. in which will there be a smaller time interval between the photographs? explain your answer.
