<span>Given:
Mass of cart: 15kg</span>
Aisle length = 14m
Angle = 17° below the
horizontal
Force fp = 12 N
So, the solution
would be like this for this specific problem:
<span><span>1)
</span>W(by applied force) = F(applied) x s x cosθ <span>
=>W(a) = 12 x 14 x cos17* = 160.66 J </span></span>
<span><span>
2)
</span>By F(net) = F(applied) - F(friction) <span>
=>As v = constant => a = 0 => F(net) = 0
=>F(applied) = F(friction)
<span>=>W(friction) = -F(friction) x s
=>W(friction) = -F(applied) x s
=>W(f) = -12 x 14 x cos17* = -160.56 J </span></span></span>
<span><span>
3)
</span>0, as the displacement is perpendicular to Force </span>
<span><span>
4)
</span>0, as the displacement is perpendicular to Force</span>
<span>
To add, the force that is applied<span> to an object by a person or another object is called
the applied force.</span></span>
