Drew bill and kieth push horizontally on chuck (100kg). drew and bill each push to the right with force 2f and keith pushes to the left with a force of f. chuck moves and accelerates to the right at 2 m/s^2 across the floor where coefficient of friction is 0.5. what is the magnitude of keith’s push?

The magnitude of Keith’s push is 230 N

Explanation:

Given:

Mass of chuck, kg

Acceleration of the chuck, m/s².

Coefficient of friction,

Frictional force acts to left as motion is to right.

Frictional force is given as:

as net force in vertical direction is zero.

Total force to the right,

Total force to the left,

Net force acting on the chuck,

According to Newton's second law,

Keith applies a force of towards left.

Therefore, the magnitude of Keith’s push is 230 N.

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.
