a pendulum with a pendulum length of 1.25 m undergoing SHM of mass 250g just released from an angel of 7 to the vertical.
(A) draw a picture and label relevant variables and known quantites.
(B) determine the period and frequency of the motion.
(C) determine the maximum pendulum bob and the time that it take to reach the speed.
(D) determine the osicilation asuming no losses due to friction or air resistance.
A tank with vertical walls, 2m wide and 2m long and 2.5 m high, is filled with 4800 litres of water (density 1000 kg/m3) and 3200 litres of light oil (density 900 kg/m3). compute the magnitude and location of the resultant force on each of the ver..
