1. Compute the locomotion transport number of a pedal-powered aircraft whose total mass (including the operator) is 126 kg. The aircraft flies at 15.0 mph when the operator is supplying 1.50 hp to the pedals.
2. It has been proposed to design a human powered vehicle (HPV) whose total mass (including the 70.0 kg operator) is only 95.0 kg. The vehicle would be capable of traveling at 64.0 km/h while the operator supplies power equal to that of a person running at 5.00 m/s. Determine the locomotion transport number of this vehicle.
A 5 kg piece of metal displaces 0.75 L of water when submerged. What is the buoyant force on the piece of metal
A modern-day zeppelin holds 9,030 m3 of helium. Compute its maximum payload at sea level. (Assume the helium and air to be at 0°C and 1 atm. The answer I get is 9391.2 kg but seems to be wrong answer and I have run out of ideas.
