b) A 0.90 kg squid initially at rest ejects 0.30 kg water vertically downwards with speed ,v = 20.0 m/s from siphons which are some parts of its body to swim upwards. By using conservation of momentum, find the speed of the squid after ejecting the water. Ignore any resistance occured. c) A standard ceiling fan requires 5.0 s to go from its common speed of 11.0 rad/s to 35.0 rad/s. i) Find the angular acceleration? ii) How many revolutions does it make in this period?
