26. Passage one and passage two describe work as a stress-free obligation to complete. Both passages send a message that gratification and satisfaction is attained by the effort put into their life duty. In passage one‚ the author’s feelings towards his grandfather were admiring. “And when I was done‚ I stood leaning my shovel for a moment‚ looking with satisfaction down the long path that stretched to the corner.” His grandfather inspired him to get his work done voluntarily with pleasure.

GEAR BOX high torque is required at the driving wheels when a vehicle is starting from rest‚ climbing a hill or accelerating. Gear set - permit the engine crankshaft to revolve at a relatively high speed while the wheels turn at slower speeds The driving force or tractive effort used must be equal to the total resistance of the forces opposing the motion of a vehicle and keeping it moving along a road at uniform speed [Air or wind resistance‚ gradient resistance‚ and Rolling resistance].

QUESTION( Conservation of Energy) 1. Missy Diwater‚ the former platform diver for the Ringling Brother’s Circus had a kinetic energy of 15 000 J just prior to hitting the bucket of water. If Missy’s mass is 50 kg‚ then what is her speed? Solution: According to energy conservation‚ the kinetic energy at the bottom of the dive (15‚000J) is equal to her gravitational potential energy before the dive. We can use this fact to find her dive height: PE = mgh h = PE/mg = 15‚000J / (50kg)(9.81m/s²)

Collisions in Two Dimensions Abstract: This lab was conducted to investigate the theories of conservation of momentum and kinetic energy in different types of 2D collisions. In order to do this‚ both an elastic and inelastic collision was conducted on an air table with pucks. A video was taken and analyzed to determine velocity‚ allowing for future finding of momentum and kinetic energy values. By finding these‚ it was possible to determine which kind of collision took place. With low values of

Question 1: Suppose you walk across a room carrying a bucket of water in your right hand. To keep the water from sloshing out‚ you walk at constant speed‚ making sure the bucket is kept at the same height above the ground. Which statement is true? a) You exert a force on the bucket and do work on the bucket as you carry it. b) You exert a force on the bucket but do no work on the bucket. c) You don’t exert a force on the bucket and you do no work on it.

Rebecca Nov. 2013 Kyle‚ Mat‚ Alex Lab M7 Conservation of Momentum Abstract: This experiment involved the use of gliders on an air track which nearly isolates the colliding system from external forces to create low friction totally elastic and inelastic collisions. Seven different collisions were made‚ four elastic and three inelastic. The collisions consisted of only two gliders with varying masses and speeds. Each glider cart was equipped with a flag‚ and its passage through a photogate
