Which statement is correct concerning the relationship between the net force acting on an object and the acceleration of that object?

Edit the post so i can see the letters for each answer, and increase the points required so i'd be able to answer it.

During the 1800s. hope this !

At maximum height, kinetic energy is converted in potential energy  formula: at max height, ke = ½ * 0.27kg * (16m/s) ² = 34.56 j  so the remaining pe = (41.70 – 34.56)= 7.14 j = 0.27 kg * 9.8m/s² * h  = (9.8/7.14 * 0.27)so max height h = 5.08 or 5 m
