A3kg box is pulled along the floor with a force of p=20 n at an angle of 30 degrees. if the box is moving at a constant velocity, calculate the force of friction f, the normal force n and the weight w.

If force is applied at 30 degree with the horizontal

then first we will find the components of force in two directions

now we can find normal force by balancing the forces in Y direction

now since block is moving with constant speed

so here forces along horizontal plane will be balanced also

Now the weight of the box is defined as

now plug in all values

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
