(Figure 1)A bob of mass mmm is suspended from a fixed point with a massless string of length LLL (i.e., it is a pendulum). You are to investigate the motion in which the string moves in a cone with half-angle θθtheta. How long does it take the bob to make one full revolution (one complete trip around the circle)? Express your answer in terms of some or all of the variables mmm, LLL, and θθtheta, as well as the free-fall acceleration ggg.
To promote his new single “Itaktak Mo”, Joe decided to launch a satellite into orbit that will intercept allairwaves and play his song worldwide. To do this, he needs to mount his 100 [kg] satellite onto a 750 [kg]rocket. It blasts off vertically from a launch pad with a constant net upward acceleration of 3.80 [m/s2].When it has reached a height of 680 [m], the satellite was released, and the rocket blew up shortly after,due to a system failure. Assume that the satellite was not damaged after the explosion. A. What is the maximum height that the satellite will reach above the launch pad? B. How much time will elapse after system failure before the satellite comes crashing down the launchpad? C. How fast will the satellite be moving just before it crashes?
