Amodel rocket is launched straight upward with an initial speed of 50.0 m/s. it accelerates with a constant upward acceleration of 2.00 m/s2 until its engines stop at an altitude of 150 m. solve the following questions:
(a) what can you say about the motion of the rocket after its engines stop?
(b) what is the maximum height reached by the rocket?
(c) how long after liftoff does the rocket reach its maximum height?
(d) how long is the rocket in the air?

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.
