Answer:

W = 13.26 [J]

Step-by-step explanation:

Work in physics is defined as the product of force by the distance traveled by the object.

It is important to clarify that the force should be parallel to the direction of movement. In this way, we have to decompose the force into the X component of the movement.

Fx = 16*cos(34) = 13.26 [N]

W = F*d

where:

F = force = 13.26 [N]

d = distance = 1 [m]

W = 13.26*1

W = 13.26 [J]
