A 20 N block is being pushed across a horizontal table by an 18 N force. If the coefficient of kinetic friction between the block and the table is 0.4, find the acceleration of the block (A.) 0.5 m/s B1.0 m/s (C) 5 m/s (D.) 7.5 m/s (E.) 9 m/s If all the forces acting on an object are balanced so that the net force is zero, then (A) The object must be at rest. (B) The object's speed will...
A 15 year old girl is riding on a playground merry-go-round, being pushed around by her friend, similar to that pictured above. The rider has a mass of 50.0 kg and a two handed grip strength of 445 N. The coefficient of friction between her and the merry-go-round is 0.100. Her friend spins her at a rate of 40 rev/min. 13. What is the frictional force, f, acting on the girl? Answer (4 points): f= 14. What is the angular...
Consider the ladder in 8.15. Compute the normal force again, assuming a 75 kg man is standing on the ladder (a) at its midpoint and (b) four fifths of the way up the latter. I posted this question earlier but was very confused on how it was answered and laid out. I am not understanding how to go about this or what formulas to use. I know the answers is (a) 130.95 N and (b) 194.2 N but I do...
Please do not choose any choice without showing the proper solutions of all questions. Q1. (a) 3 A block of mass 2.50 kg is pushed 2.20 m along a frictionless horizontal table by a constant 16.0-N force directed 25.0° below the horizontal. Determine the work done on the block by (a) the applied force, (b) the normal force exerted by the table, and (c) the gravitational force. (d) Determine the net work done on the block. Q 1. (b) 3...
Suppose the tractor pulls horizontally on the sled instead of at an angle of 36.9. As a result, the magnitude of the friction force increases to 4400N. What is the total work done on the sled? Answer: 1.20x10 J onedo 72 Work 187 SOLUTION The statement of the problem gives the hright h rather than the distance s measured along the ramp, but we can solve for h by recogsizing from the geometry in Figare 7.13 that s sinB- h....

CASE 20 Enron: Not Accounting for the Future* INTRODUCTION Once upon a time, there was a gleaming office tower in Houston, Texas. In front of that gleaming tower was a giant "E" slowly revolving, flashing in the hot Texas sun. But in 2001, the Enron Corporation, which once ranked among the top Fortune 500 companies, would collapse under a mountain of debt that had been concealed through a complex scheme of off-balance-sheet partnerships. Forced to declare bankruptcy, the energy firm...
