Answer:
The power required to move each bale is 30 lbf.ft/sec.
Explanation:
F= 40lbf * sin (30º)
F=20lbf
P= F*v
P=20 lbf * 1.5 ft/sec
P= 30 lbf.ft/sec
I believe that the correct given values are:
density = 755 kg/m^3
volume = 640 cm^3
First let us convert volume to m^3 units.
volume = 640 cm^3 * (1 m / 100 cm)^3 = 6.4 x 10^-4 m^3
so the mass is:
mass = 755 kg/m^3 * (6.4 x 10^-4 m^3)
<span>mass = 0.4832 kg = 483.2 g</span>
