Question

dart gun pushes a dart with a force of 55 N that displaces it by a distance of 9 m. Find the amount of work done on the dart. ​

Answer 1

Answer:

$\boxed{\mathfrak{Amount \ of \ work \ done\ on \ the \ dart = 495 \ J}}$

Given:

Force on dart (F) = 55 N

Displacement of dart (d) = 9 m

To Find:

Amount of work done on the dart (W)

Explanation:

Work done is product of component of the force in the direction of the displacement and magnitude of displacement.

$\boxed{ \bold{W = F.d}}$

As in the question force is acting along displacement.

So, work done on the dart:

$\sf \implies W = 55 \times 9 \\ \\ \sf \implies W = 495 \: J$

Answer 2

Answer:

F = 55 N

d = 9 m

W = F.d

W = 55×9

W = 495 J
