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.
for part c
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.
