If you were to exert a horizontal force of 200 newtons to slide a crate across a floor with constant velocity, how much friction is exerted by the floor on the crate? An object weighing 45 N rests on a surface at...
Instead of arms, the cutter has curved, claw-like extensions that come to a point. Just like in the spreader, hydraulic fluid flows into a cylinder, placing pressure on a piston. Depending on the side of the piston that force is exerted on, the claws either open or close. When the pis...
Drag, like lift, is the force exerted by the fluid against a horizontally moving object. For more information on the physics of flight, read How Airplanes Work. A skydiver exiting an aircraft will instantly experience the pull of gravity -- the force of weight. If he or she is wearing ...
A car moving at 50km/h crashes into the barrier and stops in 0.25 m a) If a 10 kg child were to be stopped in the same time, what is the average force that must be exerted b) Approximately what is the mass of an object whose weight equals t...
In Equation (2) to Equation (4), the deterministic part of the utility function for each travel mode i is defined as:(6)Vi=αi+βi∙Xiwhere αi represents the alternative specific constant (ASC) of mode i , and captures the average effect on the utility of all factors otherwise not...
To determine the force exerted on the person being ejected, we have to look at Newton's second law of motion, which states that the acceleration of an object depends on the force acting upon it and the mass of the object. Newton's second law is represented as: Force = Mass x ...
Moray eels range in sizes and colors but typically average around 5 feet long, though some species, like Thyrsoidea macrurus, can pass 11 feet. Their typical coloring and patterns range from solid black to a speckled green and help them blend into their native habitats. Oh, and those native...
If you take 1.4 kw and divide it by the speed of light, you would find that the force exerted by the sun is about 9 newtons (N)/square mile (i.e., 2 lb/km2 or .78 lb/mi2). In comparison, a space shuttle main engine can produce 1.67 million N of force during liftoff and ...
A round-bottom displacement hull looks like a large rectangle with rounded edges to dissipatedrag, or the force exerted against a moving object. The rounded edges minimize the force of the water against the hull, allowing large, heavy ships to move smoothly along. If you somehow hoisted a cru...
its mass predominates. Every object on Earth's surface is attracted to the center of the planet with a force proportional to its mass, giving rise to the adage: "whatever goes up must come down," which is true as long as the object isn't moving fast enough to leave the ground and ...
