1. What could be the energy of a flying aeroplane? 2. Is work the same as power?

Try this out. Use a calculator! We can use the formula KE=0.5m*V^2. To find the kinetic energy (KE) of a payload of mass (m) 100 kg as it flies through the air at the velocity (v) of 55 m/s. (Multiply 0.5 x the mass x velocity squared.

A 946.4 kg (2083 lb) car is moving at 14.8 m / s (33.0 mph). Calculate the magnitude of its momentum.

How do the positions of the hot and cold water affect the speed of convection

A fan is to accelerate quiescent air to a velocity of 12.5 m/s at a rate of 9 m3/s. Determine the minimum power that must be supplied to the fan. Take the density of air to be 1.18 kg/m3.
