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 $\times$ distance covered

Force = Mass $\times$ Acceleration = $0.1 kg\times 25.0 m/s=2.5 Newton$

Work done = $2.5 N\times 50.0 m=125.00 Joules$

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