An airplane flies in a loop (a circlar path in a verticalplane) of radius 150m. The pilot's head always points toward thecenter of the loop. The speed of the airplane is not constant; theairplane goes slowest at the top of the loop and fastest at thebottom.
a) At the top of the loop, the pilot feels weightless. What isthe speed of the airplane at this point?
b) At the bottom of the loop, the speed of the airplane is 280km/h. What is the apparent weight of the pilot at this point? Histrue weight is 700N.
Light of wavelength 587.5 nm illuminates a slit of width 0.75 mm. Calculate the width of the central maximum
Two people with a combined mass of 120kg hop into an old car with worn-out shock absorbers. This causes the springs to compress by 8.30 cm. When the car hits a bump in the road, it oscillates up and down with a period of 1.70s.
