Question

If the human body could convert a candy bar directly into work, how high could a 76 kg man climb a ladder if he were fueled by one bar (=1100 kJ)

Answer 1

Answer:

$1.47 \times 10^3$

Explanation:

Data provided as per the question is here below:-

Mass of the man (m) = 76 kg

Work done (W) = 1100 KJ

= $1100 \times 10^3 J$

According to the given situation the computation of height is shown below:-

$W = mgh$

so,

$h = \frac{w}{mg}$

Now we will solve the above formula

$= \frac{1100\times 10^3}{76 \times 9.8}$

$= 1.47 \times 10^3$

Therefore for computing the height we simply applied the above formula so that the correct height could come
