1.A bulldozer exerts a constant force of 7.50 x 10° N on a gigantic rock that made it move a horizontal distance of 45.0 cm. How much work is done by the bulldozer?

(PLEASE PUT THE SOLUTION PLEASE) ​


Sagot :

[tex]\tt{\huge{\blue{Explanation:}}}[/tex]

The work done by an object exerting a force F at a distance d is given by

[tex]\boxed{W = Fd}[/tex]

where:

W = work

F = force

d = distance

[tex]\tt{\huge{\red{Solution:}}}[/tex]

Solving for W

Note: 45.0 cm = 0.450 m

W = Fd

W = (7.50 × 10⁰ N)(0.450 m)

[tex]\boxed{W = \text{3.375 J}}[/tex]

Therefore, the work done is 3.375 J.
