I need help to I have a big test and I need help so bad
Volume = l*w*h = (18.1 cm)(19.2 cm)(20.3 cm) = 7,054 cm^3.
Since work is the change in kinetic energy, the efficiency of a machine can be stated as the percentage of the output work divided by the input work minus the work lost from to friction and heat. Multiply Eff by 100% to get the efficiency percentage.
It’s 49% of its original gig hope this helps!
Kinetic energy = 1/2 m v^2 = 1/2 x1.5 x10^-3 x 0.36
