A 400 kg glider is traveling at 16 m/s at a height of 200 m above the ground. Calculate the total energy of the glider if the glider drops to a height of 100 m.
Assume that there are no energy losses due to air friction and that the acceleration due to gravity at the Earth’s surface = 10 m/s2.

A.
800 kJ
B.
400 kJ
C.
450 kJ
D.
850 kJ

Use the drop-down menus to match each part of the scenario to the correct scientific practice. akira records the speed of a reaction without a catalyst and then with a catalyst. akira creates a reaction without a catalyst and repeats the reaction with a catalyst. akira turns in a written lab report to his science teacher. akira wonders, "will adding a catalyst speed up this chemical reaction? " akira writes in his notes that adding a catalyst sped up the chemical reaction because the catalyst lowers the activation energy needed to get the reaction started.
