Question

type the correct answer in the box. round your answer to the nearest whole number. calculate the man’s mass. (use $pe = m \times g \times h$, where $g = 9.8$ n/kg ) a man climbs a wall that has a height of 8.4 meters and gains a potential energy of 4,620 joules. his mass is about \boxed{} kilograms. reset next

Explanation:

Step1: Rearrange formula for mass

$m = \frac{PE}{g \times h}$

Step2: Substitute given values

$m = \frac{4620}{9.8 \times 8.4}$

Step3: Calculate denominator first

$9.8 \times 8.4 = 82.32$

Step4: Compute mass value

$m = \frac{4620}{82.32} \approx 56.12$

Step5: Round to nearest whole number

$m \approx 56$

Answer:

56
