A horizontal cord is attached to a 6.0-𝑘𝑔 body in a horizontal table. The cord passes over a pulley at the end of the table, and to this end is hung a body of mass 8 𝑘𝑔. Find the distance the two bodies will travel after 2𝑠 if they start from rest. What is the tension in the cord?

A 10-𝑘𝑔 box starting from rest is pulled using a rope that makes an angle of 30o with the horizontal. If it travels a distance of 10 𝑘𝑚 in 2𝑠, what is the magnitude of the force exerted by the rope?

A force of 60 dynes acts upon a mass of 15𝑔 a) What acceleration is imparted to the body, b) What velocity will the body acquire in 8s? c) What distance will the body cover in this 8 𝑠?

The moon has a mass of 7.32 × 1022𝑘𝑔 and a radius of 1609.4 𝑘𝑚. Calculate the value of "𝑔" at the surface of the moon.

A skier with a mass of 62 𝑘𝑔 is sliding down a snowy slope. Find the coefficient of kinetic friction for the skier if friction is known to be 45.0 𝑁.

A stockroom worker pushes a box with a mass of 11.2 𝑘𝑔 on a horizontal surface with a constant speed of 3.5 𝑚/𝑠. The coefficient of kinetic friction between the box and the surface is 0.20. a) What horizontal force must be applied by the worker to maintain the motion? b) If the force calculated in part (a) is removed, how far does the box slide before coming to rest?

An object traveling with a speed of 10 𝑚/𝑠 slides on a horizontal floor. How far will it travel before coming to rest if the coefficient of friction is 0.30?

A block of mass 3.0 𝑘𝑔 slides with uniform velocity down a plane inclined 25o with the horizontal. If the angle of inclination is increased to 40o , what will be the acceleration of the block? 

A 6.0 𝑙𝑏 box is pulled along the horizontal floor by a rope that makes an angle of 30o above the horizontal. The coefficient of kinetic friction between the box and the floor is 0.10. If the tension in the rope is 1.0 𝑙𝑏, find the acceleration of the box.
