Question

The human body gets its energy via the combustion of blood sugar (glucose). if all of the chemical bond energy in 10 g of glucose were to be released via combustion and then used to accelerate a 100 kg mass from rest, what speed would the mass attain?

Answer 1

Answer:

speed by mass attain is 55.86 m/s

Explanation:

given data

glucose = 10 g

mass = 100 kg

to find out

speed by mass attain

solution

we know glucose have 180 g molecular weight and

that 1 g glucose produce energy = 2816/180 × 10³ J

so here 10 g of glucose produce energy =  1.56 × $10^{5}$ J

so here energy release = 1/2 × mv²

1.56 × $10^{5}$  = 1/2 × (100)v²

v² = 3.12 × 10³

and v = 55.86 m/s

so speed by mass attain is 55.86 m/s
