Answer:
W = 132,167.7 J
Explanation:
given
mass = 333 kg
distance = 9.00 m
angle = 30°
external force = 4575 N (parallel to plane )
(1) work done by the external force.
w = f.d
w = 4575 × 9 = 41175 J
(2) work done by gravity.
[tex]W = -mgh \\W = -mgd \sin\theta[/tex]
[tex]W= 333 \times 9.8\times 9 \times \frac{1}{2}[/tex]
W = 132,167.7 J
