Question

BlackTom AI · Accepted Answer

Begin by restating the problem: a ball of mass 444 g is 5.1 m above the ground, find its gravitational potential energy to the nearest whole number.
First convert the mass to kilograms: 444 g = 0.444 kg.
Use the gravitational potential energy formula: PE = m g h, where g is the acceleration due to gravity (approximately 9.8 m/s^2) and h is the height (5.1 m).
Compute the product m g: 0.444 kg × 9.8 m/s^2 = 4.3512 J/m (units simplify to joules when multiplied by meters).
Now multiply by the height: 4.3512 × 5.1 m = 22.19112 J.
Round to the nearest whole number: 22 J.
Note: there are no multiple-choice options provided for this numerical question, so we follow the standard rounding rule to arrive at the final value.
