The forces
that act on the car in motion are shown in the figure. The force F has one
component in the direction of the x-axis (Fx) and another in the direction of
the y-axis (Fy). We must calculate the work (W) performed by the forces acting
in the direction of the movement.
Fx = F x Cos
(25°)
Fx = 35 N x
Cos (25°)
Fx = 31.72 N
We must use the following formula:
W = Fxd
F = 35 N
d = 50 m
W = 31.72 N
x 50 m
W = 1586.04
Nxm
W = 1586.04
J
The work
done by shwan on the cart as he moves along at 50.0 m length of aisle is
1586.04 J.
