Using a horizontal force ` 200N`, we intend to move a wooden cabinet across a floor at constant velocity. What is the frictional force that will be exerted on the cabinet?

(a)What wii be the percentage change in momentum of a body when both its mass and velocity are doubled? (b)A force of 200N is required just to move a table floor at a constant speed. What is the frictional force exerted by the floor on the table?

A block weighing 20 N rests on a horizontal surface. The: coefficient of static friction between block and surface is 0.40 and the coefficient of kinetic friction is 0.20. ( a) How large is the friction force exerted on the block? (b) How great will the friction force be if a horizontal force of 5 N is exerted on the block? (c) What is the minimum force that will start the block in motion? (d) What is the minimum force that will keep the block in motion once it has been started? (e) If the horizontal force is 10 N, what is the friction force?

A forward horizontal force of 12 N is used to pull a 240 N crate at constant velocity across a horizontal floor. The coefficient of friction is

What is the direction of force of friction acting on a moving object ?

A box of mass 20kg is pushed along a rough floor with a velocity 2 m/s and then let go .The box moves 5m on the floor before coming to rest. What must be the frictional force acting on the box? " (1) 4N (2) 2N (3) 20N (4) 8N

A person pushes horizontally with a force of 220 N on a 55 kg crate to move it across a level floor. The coefficient of kinetic friction between the crate and the floor is 0.35. What is the magnitude of (a) the frictional force?
