An airplane moves 100 m/s as it travels around a vertical circular loop which has a 1.0-km radius. What is the magnitude of the resultant force on the 50-kg pilot of this plane at the bottom of this loop? A 4.0-kg block sliding on a horizontal frictionless surface is attached to one end of a horizontal spring (k = 200 N/m) which has its other end fixed. If the block has a speed of 4.0 m/s as it passes through...

10). The cyclist shown in the figure below enters a vertical loop of radius r 15 m while traveling at an initial speed i. What is the value for the initial speed Vi so that he experiences a normal force at the top of the loop equal to his weight? Neglect friction and air resistance. He does not pedal or otherwise provide any power to his mg. nig bike as he travels around the loop.
