1. The problem statement, all variables and given/known data A projectile is launched at an angle 45degrees with respect to the horizontal and up a hill that is inclined 20degrees to the horizontal. The initial speed of the projectile is 50m/s. Neglect air resistance. a)what is maximum height? - I found 63.8m which is correct b) what is the speed of projectile 2.5s after launching? - 37m/s which is correct c) find the distance up the hill the projectile lands. d)calculate the magnitude and direction of the velocity of the projectile at impact. 2. Relevant equations for part c x=vicos(45)t-.5gsin(25)t^2 x=visin(45)t-.5gcos(25)t^2 3. The attempt at a solution The only idea i have for part c is to change the x-y axis so that x is along the slope. Any help solving or ideas would be great.
