I am compleatly lost on these two KE Work-Energy Theorem Problem questions any feedback or help would be greatly appreciated. Thank you in advance...... 1.) 47.0 g golf ball is driven from the tee with an initial speed of 52.0 m/s and rises to a height of 25.0 m. (a) Neglect air resistance and determine the kinetic energy of the ball at its highest point. J (b) What is its speed when it is 10.0 m below its highest point? m/s 2.) A fighter jet is launched from an aircraft carrier with the aid of its own engines and a steam-powered catapult. The thrust of its engines is 1.8 105 N. In being launched from rest it moves through a distance of 87 m and has a kinetic energy of 4.7 107 J at lift-off. What is the work done on the jet by the catapult? Thanks!
