You push horizontally on the crate with a varying force F to move distance d= 4.00m to the side a) What the mairnitude of F when the crate is in this final position? During the crate's displacement, what are b) the total work done on it, c) the work done by the gravitational force on the crate, and d) the work done by the pull on the crate from the rope? e) Knowing the crate is motionless before and after its displacement, use the answers to (b), (e), und (d) to find the work your force F does on the crate. f) Why is the work of your force not equal to the product of the horizontal displacement and the answer to (a)?
Unreasonable Results - A slightly deranged Arctic inventor surrounded by ice thinks it would be much less mechanically complex to cool a car engine by melting ice on it than by having a water-cooled system with a radiator, water pump, antifreeze, and so on. (a) If 80% of the energy in 1.00 gal of gasoline is converted into “waste heat” in a car engine, how many kilograms of 0C ice could it melt? (b) Is this a reasonable amount of ice to carry around to cool the engine for 1.00 gal of gasoline consumption? (c) What premises or assumptions are unreasonable?
Please indicate the given, assumption and illustration. A Jet plane having a wing area of 20 m2 and weighing 25 kN flies at 950 km/hr speed. The engine develops 8,500 kW and has a mechanical efficiency of 9%. With the specific weight of air at 12 N/m3, determine the following: A) The Coefficient of Lift (CL). B) The Coefficient of Drag (CD).
An arborist is cutting down a tree a 28 m high tree bystarting his cut 1.8 m above the ground. The tree has a mass of 3750 kg. The tree trunk can be thought of as a uniformly dense, thin rod. 1. What's the speed of the tree’s center of mass when the trunk is parallel to the ground on its way down. The tree rotates about the point where it is cut., 1.8 m above the ground. 2. What is the total amount of kinetic energy that the tree has at thatpoint of parallelism to the ground? How fast would a 950.0 kg truck have to be traveling to have the same kinetic energy as the tree?
