Aball moves along a 1d coordinate system with the following motion parameters at time t = 0 s: xo 7.1 mand vo 0 m/s. the ball has a constant acceleration of 2.5 m/s2 during the entire motion which occurs over a time of 2.6 s. assume that an error in position of 4 % is acceptable in this application over the entire motion. how many rows n will be needed in the table to model the entire motion to within the required error even though you are leaving out the final term of 1/2 a (at )2) present in the exact position expression?

We will use a video to study faraday’s law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will: examine some of the main principles behind faraday’s law. apply lenz’s law to determine the direction of the induced emf. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. use the horizontal scale provided to determine the speed of the coil. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.
