How much work is performed when a 50kg is pushed 15m with a force of 20n?

Answer 1

That depends also on the direction of force, though it simplifies greatly if force is all the way applied exclusively in the direction of movement.

Work doesn't depend on the mass too.

Formula is(assuming the direction of applied force is the same as of displacement):

W = F * r, where

W - work,

F - force,

r - displacement.

For given data, it will be:

W = 20 * 15 = 300 J

Answer 2

A force of 40 N that acts through a distance of 15 m does (40 x 15) = 600 joules of work.

It makes no difference what the purpose of the force is, whether it's pushing a

crate, a car, or an elephant, what the crate's mass or color is, what time of day

the operation is performed, or whether the pusher is male or female.

Answer 3

If a force of 20 N acts through a distance of 15 m, then it does (20 x 15) = 300 joules of work.

The other facts of the case, such as the mass of the crate being pushed, don't matter.

Answer 4

When a 50-newton force acts through 15 meters in the direction of the force,

it does (50 x 15) = 750 newton-meters = 750 joules of work.

Answer 5

Work = (force) x (distance)

(40 N) x (15 m) = 600 newton-meters = 600 joules.

The mass and weight of the crate are irrelevant.

Answer 6

The work done is calculated by multiplying force with distance in the direction of the force. In this case, work = force x distance = 20N x 15m = 300 Joules.

Answer 7

force * distance = 20 * 15 = 300 n-m

Answer 8

ke = 600joules

Answer 9

450 j
