1) A crude cannonball launcher is constructed using a 45? inclineand a spring, as shown in Fig.-1. When the spring is compressed,the center of the cannonball is 1.50 m off the ground, as shown inFig.-1a. When the spring is let go, it expands to its equilibriumposition, as shown in Fig.-1b. At this point, the cannonball isjust leaving the incline, and its center is 3.00 m off the ground.If the mass of the cannonball is 10.0 kg, and the force constant ofthe spring is 200 N/m, find the horizontal distance that thecannonball lands from point A. Neglect all friction, and all massesexcept for the mass of the cannonball.
this is the problem that i tried but i dont know how to start it
