A projectile is launched with speed v0 from point A. Determine the launch angle Ɵ which results in the maximum range R up the incline of angle α (where 0 ≤ α ≤ 90 ˚ ) Evaluate your results for α = 0 , 30˚,and 45˚.

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.
