A rope is attached to Box A, and it is pulled on a rough surface due east with friction. The mass of Box A is 50 kg, and the tension force applied to the box is 100 N due east. If Box A is pulled by the tension force for 4.0 s, and the velocity changes from 0.1 m/s due east to 0.65 m/s due east during the time Box A is pulled, answer the following questions.  (a) What is the acceleration of Box A during the time it is pulled?  (b) What is the change in kinetic energy of Box A during the time it is pulled?  (c) What is the net work done on Box A by the tension force and the frictional force together? (d) What is the work done on Box A by the tension force alone?  (e) What is the work done on Box A by the frictional force alone?

A cable attached to a block of mass 13 kg pulls the block along a horizontal floor at a constant velocity. If the tension in the cable is 5.1 N, what is the coefficient of kinetic friction between the block and the floor?

A block is at rest on a horizontal floor. There is friction between the block and the floor. The block has a mass = 5.00 kg. A horizontal force of 13.0 Newtons is applied to the block and the block starts to move in the direction of the force. What is the coefficient of static friction?

In the figure here, a box of Cheerios (mass mc = 1.70 kg) and a box of Wheaties (mass mw = 2.60 kg) are accelerated across a horizontal surface by a horizontal force applied to the Cheerios box. The magnitude of the frictional force on the Cheerios box is 2.10 N, and the magnitude of the frictional force on the Wheaties box is 4.60 N. If the magnitude of F is 12.7 N, what is the magnitude of the force on the Wheaties box from the Cheerios box? Number i Unit

If a mass of 3.46 kg object is attached to a string. If the force of tension in the string is 50.2 N j, what is the magnitude of the object's acceleration?

Two objects are connected by a massless cable passing over a frictionless pulley. Object A is positioned on a table, while object B hangs freely. The coefficient of kinetic friction between object A and the table is 0.09950. If the mass of object A is 150 kg, and the mass of object B is 238 kg, what is the acceleration of the objects?

Two people are pushing a truck across a parking lot. The truck has a mass of about 2 × 103 kg. First, they take turns pushing. When Person A pushes the truck, the truck accelerates at a rate of 1 m/s2. When Person B pushes the truck, it accelerates at a rate of 2 m/s?. (a) Both people stand behind the truck and push in the same direction. What is the net force on the truck? At what rate will the truck accelerate? (b) Person A stands at the back of the truck and Person B stands at the front, and they push in opposite directions. What is the net force on the truck? At what rate will the truck accelerate? In what direction? For both (a) and (b), draw a picture indicating the forces applied by A and B as well as the motion of the truck.

A 34.8 kg child is sitting at the top of a slide, which is inclined at an angle of 55 degrees with respect to the horizontal. Someone gives the child a quick push to get them moving, after which they slide down the incline without any further assistance. The coefficient of kinetic friction between the child and the slide is μ s  = 0.44. What is the magnitude of the acceleration (in m/s2) of the child?
