Atruck accelerating at 0.0083 meters/second2 covers a distance of 5.8 × 104 meters. if the truck's mass is 7,000 kilograms, what is the work done to reach this distance?

The correct answer to the question is

CALCULATION:

The acceleration of the truck is given as a =

The mass of truck is given as m = 7000 kg.

The distance travelled by the truck S = .

The force applied on the truck is calculated as -

                            Force F = mass × acceleration

                                      =

                                      = 58.1 N.

We are asked to calculate the work done .

The work done by a body is calculated as -

                                              W =

                                                   =

Here, is the angle between force and displacement.

If , then W = FS

Hence, the work done by the truck W = FS

                                                               =

                                                               =

Here, J ( joule ) is the unit of work.

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.
