The total work done or energy transferred is equal to the product of the force and the displacement in the direction of the force applied. In this case it would be 300N x 10m to get 3000J. This energy is transferred in 10 seconds and since power is energy transferred per unit time... 3000J divided by 10 seconds equals 300 Watts or 300 Joules per second.
Force = mass * acceleration Force = (3000 kg)*(2 m/s^2) = 6000 Newtons ---------------------- ( that is 6000 times the force needed to push in a doorbell, on average )
If an object does not move, no work is performed. Work is performed by a force acting through a distance.
The work done on the box is given by the formula work = force x distance. More information is needed to calculate the total work done on the box as the amount of force exerted to move the box is required.
The work done to move a 10N book 5 meters is 50 Joules. This is calculated by multiplying the force (10N) by the distance (5 meters) moved in the direction of the force.
force x distance = work 30 N x 0.5 metres = 15joules

The work done is calculated as the product of force and displacement, W = F * d. Therefore, 75 N * 8 m = 600 J of work is done when a force of 75 N is applied to a table causing it to move 8 meters.
To calculate the work done, you would multiply the force applied (2.5 N) by the distance moved (7 m). Work = Force x Distance. So, the work done to move the dresser 7 meters with a force of 2.5 newtons would be 17.5 joules.
Power is calculated as work done divided by time taken. The work done is force multiplied by distance, which in this case is 200 N * 10 m = 2000 J. Plugging in the values, the power required would be 250 Watts.
Your power output would be 100 Watts. This can be calculated by dividing the work done (force x distance) by the time taken to do the work (10 seconds).
When a force makes an object move, work is done.

The work required to move the truck is 600 N (600 kg-m/sec2) times 30 meters = 18000 joules. If this is done in 15 seconds, the average power was 1200 watts (kg-m2/sec3).
No, work is not done if the force is applied to a mass but the mass does not move. Work is only done when a force causes a displacement in the direction of the force being applied.
