1. The problem statement, all variables and given/known data A projectile is launched at an angle 45 degrees above the horizon with a velocity of 30 m/s. It is launched at the base of a constant slope, which has an angle of 30 degrees. a- How much time did it take for the projectile to hit the slope? b- Where did the projectile hit the slope? Use a vector. c- Was the projectile moving up or down when it hit? 2. Relevant equations t = 2 V sin angle /g x= V^2 sin 2angle / g 3. The attempt at a solution a- (2(30 m/s) sin 15)/ 9.8 m/s^2 t = 1.58 s b- (30 m/s (cos 15) ) i + (30 m/s (sin 15)) j I am not sure I should be using 15 as the angle for part b. I tried with 30 and 45, and 30 seems like the right coordinates considering the picture I drew.
