In the lab we saw that we are making the cart move with the help of a battery powered fan attached on the cart. Suppose the track is nearly frictionless and very long. We turn on the fan, let it run for sometime, then turn it off. We see that the cart O gradually slows down and comes to a stop. O gradually slows down and continues with constant velocity. O just continues with constant velocity slows down, stops, then starts going in the opposite direction.

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

You want to figure out just how crazy a driver your friend is. As one of many stop lights begins to change green, you produce a small metal ball on a string and let the ball hang down. As usual, your friend floors the accelerator and you note that while the car is accelerating, the ball sweeps back toward the back of the car so that the ball’s string makes an angle of about 35 degrees with the vertical. What is acceleration of the car in both meters per second squared and in terms of g’s (an acceleration equivalent to what multiple of Earth’s gravitational acceleration g)?

Archibald, an aging geezer, is out bicycling one fine afternoon, reliving his glorious youth and oblivious to the world around him. As he approaches a busy intersection, a police officer directing traffic blows his whistle to get Archie’s attention so he’ll slow down and stop. But Archie doesn’t stop; he just speeds right through the intersection as if the traffic cop wasn’t even there. The cop radios one of his colleagues and gets her to stop the old geezer. She gives him a traffic citation for failing to heed the command of a police officer directing traffic. When the case gets to traffic court, Archie explains to the judge that he didn’t hear the officer’s whistle because he is going deaf and cannot hear frequencies above 3000 Hz. The traffic cop informs the judge that his standard issue police whistle emits a frequency of 2100 Hz and he has a certificate to prove it. Thinking quickly (at least for an old geezer) Archie says that it may be true that the police whistle emits a sound…

You want to visit your friend in Seattle and decide to take the train. Unfortunately, you are late getting to the train station. You are running as fast as you can, but 30 meters ahead of you the train begins to pull out. You can run at a maximum speed of 8 m/s and the train is accelerating at 1 m/s². In 50 meters you will reach a barrier. Can you catch up to the departing train? Argue why you should or should not jump onto the moving train?
