Homework Statement



An object is launched at x m/s from a 1.7526 meter platform. How much energy must be exerted for the object to be launched 1.8288 meters?

Homework Equations



Not Sure

The Attempt at a Solution



I made a right triangle and found that the hypotenuse (or distance that the object will need to travel) is 2.532888 meters.

hi sfishman59! welcome to pf! :wink:

do you mean that the object is launched at an unknown angle from 1.7526 m above the ground, and has to land on the ground 1.8288 m away?

the hypotenuse has nothing to do with it

call the initial speed v and the initial angle θ, and use the standard constant acceleration equations in the x and y directions (separately, with a = 0 and a = -g) …

show us what you get :smile:​
