Airplanes need a longer runway at high altitudes to develop the required lift Please explain?
The airplane develops lift through the process of moving a mass of air over the wings at a sufficient rate ... the more mass per second, the more lift. The density of air is less at high altitudes, meaning any given volume has less mass than the same volume would have at lower altitude. In order to blow the required amount of mass (per second) over the wings and develop the required lift, more speed is required, hence a longer runway over which to accelerate.
What is the power rating of a machine to lift a crate in 5 seconds?
That really depends on the weight of the crate. Also, on how high you want to lift it. Calculate the energy required to lift the crate with the formula for gravitational potential energy: PE = mgh (mass x gravity x height) Then divide this by the 5 seconds to get the minimum power required. (The actual power is somewhat larger, for various reasons - the initial acceleration required, and losses due to friction.)
How much force to lift 50 kilograms onto a shelf 3 meters high?
The height is irrelevant. The energy required depends on the height; the force does not. The weight of an object, and therefore the force required to lift it, is mass x gravity - about 500 Newtons.The height is irrelevant. The energy required depends on the height; the force does not.

What effort is required to lift a 300 kg weight?
On earth, any vertical force greater than 661.39 pounds will lift a mass of 300 kg.
Will the mass change at a very high speed compared the speed of light?
Yes. According to the extended theory of relativity, mass will increase as an objects speed increases. The closer the object's speed gets to the speed of light, the greater its mass will be and a greater force will be required to continue to accelerate it.
How does mass and speed relate to kinetic power?
Kinetic energy (not power) is given by 1/2 x Mass x Velocity2
Difference between car speed and truck speed?
The only difference is the energy required to obtain the same speed. The extra weigh of a truck means that more energy is required to move the greater mass as Force = Mass x acceleration (F = MA). Thus if more mass is being accelerated more force is required. Speed = distance travel / time taken to travel. (S = D/T) Thus speed would be the same for a car and a truck.
What is the bashing power of an object?
The "bashing power" that you speak of is a combination of the mass that you are bashing with combined with the speed of the mass. It is expressed in the form E=MC2.
How does mass affect speed?
== F=m*a Force = mass * speed a = F/m For the same Force F the speed is big for small mass the speed is small for big mass == The more mass something has, the more force is required to accelerate it to a given speed. The less mass something has, the less the force required to accelerate it to a given speed. Simple and easy. For a given amount of force, the less the mass it is applied to, the higher the speed that will result. The more the mass to which it is applied, the lower the speed that will result. It's just that simple.
What are 3 factors that affects the speed of the solenoid?
Mass (inertia), friction, & power of the coil.
How do mass and inertia make it easier to pick up an empty juice bottle than a full juice bottle?
The principal of inertia merely says that a body will remain ar rest until moved by a force. The force required to lift a bottle has to be equal and opposite to the force of gravity pulling it down which is proportional to its mass. So the more mass in the bottle the more force required to lift it.
What 2 factors determine how much kinetic energy something has?
Good guess but the real answer is mass and speed.
