A rose-covered parade float is at x = 0 at time t = 0. The float moves in a straight line at 2.0 m/s for the next 5 s before coming to
a stop. After a 5-s stop, the float moves again at 1.0 m/s in the same
direction as before.
(a) Sketch the position-time graph for the float from the time t = 0
until the time t = 15 s.
(b) From your graph, determine the positions of the float at t = 2 s
and t = 11 s.

*drag each tile to the correct location in the sequence* the table shows chronological events in the life of our sun, a medium-sized star. place the missing events into the correct rows of the table.

When the displacement of a mass on a spring is 12a the half of the amplitude, what fraction of the mechanical energy is kinetic energy? at what displacement, as a fraction of a, is the mechanical energy half kinetic and half potential?

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.
