Just asking help with Part I
A factory worker pushes a 30.0 kg crate a distance of 4.40 m along a level floor by pushing downward at an angle of 28.0° below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.260. The Crate is Pushed with Increasing Speed Now assume that, instead of the previous situation, the worker pushes harder (without changing the direction of his push), so that the crate moves with increasing speed....

There are (one can say) three coequal theories of motion for a single particle: Newton's second law, stating that the total force on an object causes its acceleration; the work-kinetic energy theorem, stating that the total work on an object causes its change in kinetic energy; and the impulse-momentum theorem, stating that the total impulse on an object causes its change in momentum. In this problem,...

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....
