The pushing force is horizontal, with magnitude P, and the coefficient of kinetic friction between the crate and the incline is μ = 0.358. Consider the work done on the crate as it moves a distance d = 5.32 m at constant speed. a. What is work done by the pushing force, in joules?  b. What is the work done by friction, in joules?  c. What is the work done by gravity, in joules?  d. What is the net work, in joules?

A 2.11 kg cart moving along a horizontal track in the positive x direction has a changing force exerted on it. The force exerted on the cart is plotted in the graph shown. In the plot, Fmax has a value of 5.95 Newtons. Note that the friction between the cart and track is negligible. a.-Calculate the work done on the cart when it has reached a displacement of 21.3 cm along the track.  b.- If the cart starts from rest, calculate how fast the cart is going when it has reached a displacement of 21.3 cm along the track.

You push your physics book 2.40 m along a horizontal tabletop with a horizontal push of 3.00 N while the opposing force of friction is 0.700 N. a. How much work does your 3.00 N push do on the book? b. How much work does the normal force from the table do on the book? c.

The force on a particle is directed along an x axis and given by F = Fo(x/xo - 1) where x is in meters and F is in Newtons. If Fo= 1.4 N and xo = 2.3 m, find the work done by the force in moving the particle from x = 0 to x = 2x0 m. Number i Units

How do you know if the work done by a force acting on an object is positive or negative? Hint: Work is a scalar but both force and displacement are vectors.

Object A is stationary while objects B and C are in motion. Forces from object A do 12 J of work on object B and -5 J of work on object C. Forces from the environment do 4 J of work on object B and 8 J of work on object C. Objects B and C do not Part A interact. What is AKtot if objects A, B, and C are defined as separate systems? Express your answer in joules as an integer. View Available Hint(s) ΑΣφ AKtot = J
