Your moving company is to load a crate of books on a truck with the of some planks that slope upward at the mass of the crate is 100 kg, and the coefficient of sliding friction between it and the planks is 0.500. you and your employees push horizontally with a combined net force once the crate has started to move, how large must f be in order to keep the crate moving at constant speed?

the force must be larger than F= 490N for example for a speed of 1m/s for 10s the force is 590N

Explanation:

The motion of the truck must be bigger than the Fk of friction that is opposite of the force both person are doing so:

Knowing the truck must be accelerated to get a constant speed the acceleration can be determinate by

It is at rest so

The force net of both person is

Asume for example that the speed they want is about 1 m/s for 10 s so the force have to be larger than 490N

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.
