PHYS 1403 LAB HOMEWORK Friction This homework will be due at 11:59 PM on Friday, July...
A 10 kg crate is pulled along a warchouse floor across a distance of 35 m by a horizontal rope. The force of the rope is 22.0 N; the block starts from rest. At the end of the 35 m, the final velocity of the block is 1.8 m/s. What is the coefficient of kinetic friction? (15 pts)
PHYSICS 1403 Lab Homework - Statics This homework will be due at 11:59 PM on Monday, August 3. The crew on Peg Leg Pete the Pirate's ship have mutinied. Now Pete finds himself walking the plank. The plank is 5.50 m long and has a mass of 18 kg. 3.60 meters of the plank extend out over the shark infested waters of the bay. The plank pivots on a small rail at the edge of the ship (3.60 m from...
Springing Off the Table
Due this Friday, Nov 13 at 11:59 pm (EST)
A 0.272-kg box is placed in contact with a spring of stiffness
4.352×102 N/m. The spring is compressed 1.08×10-1 m from its
unstrained length. The spring is then released, the block slides
across a frictionless tabletop, and it flies through the air. The
tabletop is a height of 1.060 m above the floor.

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 person pulls on a 7.8 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 1.3 m/s and speeded up to 2.5 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 mass m = 17 kg is pulled along a horizontal floor with NO friction for a distance d =5.8 m. Then the mass is pulled up an incline that makes an angle 0 = 35º with the horizontal and has a coefficient of kinetic friction uk = 0.38. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of 0 = 35° (thus on the incline it is parallel...
A person pulls on a 9.3 kg crate as it slides across a level floor with coefficient of kinetic friction 0.5 using a rope attached to the center of the crate. The crate began with a speed of 1.6 m/s and speeded up to 2.7 m/s while being pulled a horizontal distance of 2.0 meters. What is the net change in the kinetic energy in J of this crate during that period?
Problem 04 ed A 244-kg crate is being above the horizontal. The coefficient of kinetic friction is 0.2. If the crate is moved a distance of 45 m calculate across a horizontal floor by a force P that makes an angle 8-32.5 P 150ON 244 Kg [Hint draw a free body diagram and find the friction force] a) the work done by the net force. b) If the block was initially at rest compute its speed upon reaching 45 m
A mass m = 16 kg is pulled along a horizontal floor with NO friction for a distance d =7.5 m. Then the mass is pulled up an incline that makes an angle θ = 33° with the horizontal and has a coefficient of kinetic friction μk = 0.41. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 33° (thus on the incline it is parallel...
