Answer
To calculate the potential energy (PE) of the sledder at the top of the hill, we can use the formula for gravitational potential energy:<br /><br />\[ PE = mgh \]<br /><br />where:<br />- \( m \) is the mass of the sledder (60 kg),<br />- \( g \) is the acceleration due to gravity (approximately 9.8 m/s²),<br />- \( h \) is the height of the hill (52 meters).<br /><br />Plugging in the values:<br /><br />\[ PE = 60 \, \text{kg} \times 9.8 \, \text{m/s}^2 \times 52 \, \text{m} \]<br /><br />\[ PE = 60 \times 9.8 \times 52 \]<br /><br />\[ PE = 30576 \, \text{J} \]<br /><br />Therefore, the potential energy of the sledder at the top of the hill is:<br /><br />\[ 30,576 \, \text{J} \]<br /><br />So, the correct answer is:<br /><br />\[ \boxed{30,576 \, \text{J}} \]
