write down the relationship for finding the range and time of flight for a projectile fired with an initial velocity of U and at an angle of elevation of 0. A body projected upward at an angle of 30° with the horizontal has an initial speed of 90ms^-1. In how many seconds will it reach the ground?.How far from the point of projection will it strike the ground?.At what angle with the horizontal will it strike?

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.
