Unformatted text preview: another linearly indepdent solution ! ! ! = ! ! ! ! ! . Please note that ! ! ! , ! ! and ! ! are given functions while ! ! is not. Q22 (5 points): Find the general solution of the following DE: ! ! ! + 2 ! ! + ! = 5 ( sin ! + cos ! ) Q23 (5 points): If a projectile leaves Earth’s surface at velectiy ! ! , please derivate the formula for the later velocity as a function of the distance ! from the projectile to the center of the earth. The earth’s radius ! and gravitational constant ! are given ( 3 Points ). Also, naturally, the velocity has to be a real number. Compute the condition at which the velocity will become imaginary ( 2 Points )....
