A person pulls a 50-kg crate over a displacement of 40-m along a horizontal floor with a rope of 100N tension. The rope makes an angle of 37o with the horizontal surface. The floor is rough, exerting a friction force of 60 N. (a) Determine the work done by each of the forces acting on the crate. (b) Determine the final speed of the crate assuming it started from rest.

A worker pushes a 27.0kg crate a distance 9.50m along a level floor at constant speed by exerting a pushing force on the crate which is directed 35.0◦ below the horizontal. The coefficient of kinetic friction is 0.230. (a) How much work did the worker do on the crate? Now the worker pushes the same crate up a 35.0◦ incline at constant speed, with the same kinetic friction coefficient. This time the worker pushes horizontally on the crate. Over the...

Homework The history of performance automobile design and production has been characterized by trying to get more speed for less power. High power engines are heavy, require more cooling, and consume fuel at a high rate. It is therefore advantageous for a race car to have an aerodynamic body to reduce drag. This assignment will walk you through how to estimate the top speed of a car given that we know the power rating of the engine and a few...
