Answer:
B. Sled B has more potential energy.
Explanation:
Option B is correct because when you carry out the calculation, you will find out.
Below is the calculation:
Potential energy = mgh where m= mass of sled, g=gravitational force =[tex]9.8m/s^{2}[/tex] and h= height.
Sled A Potential Energy = 100kg x [tex]9.8m/s^{2}[/tex] x 50m = [tex]49000kgm^{2}/s^{2}[/tex]= 49kJ.
Sled B Potential Energy = 200kg x [tex]9.8m/s^{2}[/tex] x 30m = [tex]58800kgm^{2}/s^{2}[/tex] = 58.8kJ.
So, since Sled B gave us 58.8kJ, it has more potential energy than Sled A that has 49kJ.
