sally applies a horizontal force of 462N with a rope to drag a wooden crate across a floor with...
Homework Answers
Work done by sally = F cos 56 * d ;
W = 462 * cos 56 * 24.5 = 6329.5 J
since the KE remains constant ,
W net = 0 ;
W friction = - W sally ;
W friction = -6329.5J<-------------ans

Work on a sliding crate. A worker pushes a 47.0 Kg crate across a level horizontal floor by applying a constant force of exactly 150.0 N at an angle of 23.0 degrees below the horizontal. The crate begins at rest and ends 15.0m from where it started traveling at 2.6m/s A. What is the work done by the applied force as the crate moves across the floor? B What is the work done by the friction force as the crate...

A person pulls on a 8.7 kg crate as it slides across a level floor using a rope attached to the center of the crate. The floor has a non-zero coefficient of kinetic friction. The crate began with a speed of 1.4 m/s and speeded up to 2.4 m/s while being pulled a horizontal distance of 2.0 meters. If the force exerted by the rope is 20 Newtons, and the rope pulls completely horizontally, what is the work in J...

A person pulls on a 9.4 kg crate as it slides across a level floor using a rope attached to the center of the crate. The floor has a non-zero coefficient of kinetic friction. The crate began with a speed of 1.9 m/s and speeded up to 2.8 m/s while being pulled a horizontal distance of 2.0 meters. If the force exerted by the rope is 20 Newtons, and the rope pulls completely horizontally, what is the work in J...

A 96kg crate, starting from rest, is pulled across a floor with a constant horizontal force of 350N. For the first 15m the floor is frictionless, and for the next 15m the coefficient of friction is 0.25. What is the final speed of the crate? PLEASE ANSWER USING CONSERVATION OF ENERGY IF POSSIBLE!
A 20.0-kg crate, starting from rest, is pulled across a floor with a constant horizontal force...
A 20.0-kg crate, starting from rest, is pulled across a floor with a constant horizontal force F. for the first 9.00 m the floor is frictionless, and for the next 12.0 m the coefficient of friction is 0.200. The final speed of the crate after being pulled these 21.0 m is 18.0 m/s. How much is the constant horizontal force F mentioned above?
A worker drags a crate across a factory floor by pulling on a rope tied to...
A worker drags a crate across a factory floor by pulling on a rope tied to the crate. The worker exerts a force of magnitude F = 460 N on the rope, which is inclined at angle θ = 35° to the horizontal, and the floor exerts a horizontal force of magnitude f = 100 N that opposes the motion. Calculate the magnitude of the acceleration of the crate if (a) its mass is 360 kg and (b) its weight...
