Problem $4$: A cylindrical tank of methanol has a mass of $40kg$ and a volume of $51L.$ Determine

the methanol's weight, density, and specific gravity. Take the gravitational acceleration to be $9\mathrm{.}81$

$\frac{m}{s}2.$ Also, estimate how much force is needed to accelerate this tank linearly at $0\mathrm{.}25\frac{m}{s^2}.$
