Question

If a mass of 100.0g moves through a distance of 50.0 m with an acceleration of 25.0 m s`, how much work was necessary to move the mass?

Answer 1

Answer : Work done to to move the mass is 125 J.

Solution:

Mass of the object = 100.0 g = 0.1 Kg ( 1 Kg=1000 g )

Acceleration with which object is moving = 25 m/s

distance covered by the object = 50 m

Work done to the mass = Force
`*` distance covered

Force = Mass
`*` Acceleration =
`0.1 kg* 25.0 m/s=2.5 Newton`

Work done =
`2.5 N* 50.0 m=125.00 Joules`

So, the work done to to move the 0.1 Kg mass is 125 J.
