Read the paragraph multiple times and find the main ideas and supporting details. Find what it is mostly about and compare the information you have to the statements and select the one most like yours. This is the best I can do without seeing any of the choices and the paragraph. Hope this helps! :)
I think it’s cannot be determined
PE equals KE when KE is 50%.
Like below:
E = PE + KE
E = 50 + 50
E = 100.
Remember, both KE and PE always have to add up to 100 so that is why PE is equal to KE when KE is 50% of energy.
Hope I helped. :)
Centripetal acceleration is given by the formula

Since we know the value of the acceleration is 9.8 m/s² and we know r, we can solve for the speed, which is the magnitude of v. Note the value of a is just the acceleration due to gravity, which is what makes the rocket orbit and not fly off into space.
Answer: example 1: increase force applied to object. Example 2: Increase distance over which work applied. Example 3: Change direction of applied force.
