A50.-newton horizontal force is needed to keep an object weighing 500. newtons moving at a constant velocity of 2.0 meters per second across a horizontal surface. the magnitude of the frictional force acting on the object is

The magnitude of the frictional force acting on the object is 50 N.

Given :

Horizontal Force = 50 N

Object weight = 500 N

Constant Velocity = 2 m/sec

Solution --

Constant velocity means acceleration is zero. And from Newton's second law of motion,

 ---- (1)

Here a = 0, therefore from equation (1) we get:

where is friction force,

The magnitude of the frictional force acting on the object is 50 N.
