A factory worker pushes a crate of mass 32.0 kg a distance of 4.20 m along a level floor at constant velocity by pushing horizontally on it. The coefficient of kinetic friction between the crate and floor is 0.25. What magnitude of force must the worker apply? Express your answer using two significant figures. F = N Part B How much work is done on the crate by this force? Express your answer using two significant figures. W = J ...
A child pulls a block across the floor with force applied by a horizontally held string....
A child pulls a block across the floor with force applied by a horizontally held string. A smaller frictional force also acts upon the block yielding a net force on the block that is smaller than the force applied by the string. How does the work done by the string compare with the change in the block’s kinetic energy? the work done is greater than the change in the kinetic energy of the block The work done is equal to...

One way to measure the amount of energy that a moving object (auch as a car) possesses is by finding its Kinetic Energy. The Kinetic Energy (Es, measured in Joules) f am object depends on the objects mass m measured in kg) and velocity (v, measured in meters per second), and can be written as - What is the Kinetic Enerzy of an object with a mass of 1,700 kilograms that is traveling at 30 meters per second? Joules Points...

A box of mass 40 kg is initially at rest on a flat floor. The coefficient of kinetic friction between the box and the floor is µk = 0.40. A woman pushes against the box with a force of 250 N that makes an angle of 30° with the horizontal until the box attains a speed of 1.0 m/s. (a) What is the change of kinetic energy of the box? (b) What is the work done by the friction force...
